It has three different memory access buses (SFR, DATA, and CODE/XDATA), a debug interface, and an 18-input extended interrupt unit. The memory arbiter is at the heart of the s ystem, as it connects the CPU and DMA control ler with the physical memories and all peripherals through th e SFR bus. The memory arbiter has four memory -access points, access of which can map to one of three physical memories: an SRAM, flash memory, and XRE G/SFR registers. It is responsible for performing arbitration and sequencing between simultaneo us memory accesses to the same physical memory. The SFR bus is a common bus that connects all hardware peripherals to the memory arbiter. The SFR bus also provides access to the radio registers in the radio register bank, even though these are indeed mappe d into XDATA memory space. The 8-KB SRAM maps to the DATA memory space and to parts of the XDATA memory spaces. The SRAM is an ultralow-power SRAM that retains i ts contents even when the digital part is pow ered off (power modes 2 and 3). The 128 KB flash bl ock provide s in -circuit programmable non -volatile program memory for the device, and maps into the CODE and XDATA memory spaces.

4 Certifications

4.1 Bluetooth

BLED112 Bluetooth low energy module is Bluetooth qualified and listed as an End Product.

4.2 FCC and ISED (Formerly IC)

The BLED112 dongle is approved for the USA and Canada markets and comes with the following grant and certificate IDs: FCC ID: QOQBLED112 IC: 5123A-BGTBLED112

4.2.1 FCC

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installe d and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur i n a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help FCC Caution : To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

4.2.2 ISED (Formerly IC)

IC Statements: This device complies with Industry Canada licence -exempt RSS standard(s). Opera tion is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. T o reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the eq uivalent isotropically Déclaration d’IC : Ce dispositif est conforme aux normes RSS exemptes de licence d’Industrie Canada. Son fonctionnement est assujetti aux deux c onditions suivantes : (1) ce dispositif ne doit pas provoquer de perturbation et (2) ce dispositif doit accepter toute perturbation, y compris les perturbations qui peuvent entraîner un fonctionnement non désiré du dispositif. Selon les réglementations d’I ndustrie Canada, cet émetteur radio ne doit fonctionner qu’avec une antenne d’une typologie spécifique et d’un gain maximum (ou inférieur) ap prouvé po ur l’émetteur par Indu strie Canada. Pour réduire les éventuelles perturbations radioélectriques nuisibles à d’autres utilisateurs, le type d’antenne et son gain doivent être choisis de manière à ce que la puissance isotrope rayonnée équivalente
