4973AS–GPS–12/07 ATR0622P1 1. Description The GPS baseband processor ATR0622P1 includes a 16-channel GPS correlator and is based on the ARM7TDMI processor core. This processor has a high-perfo rmance 32-bit RISC architecture and very low power consump- tion. In addition, a large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications. The ATR0622P1 has two USART and an USB device port. This port is compliant with the Universal Serial Bus (USB) V2.0 full-speed device specification. The ATR0622P1 includes full GPS firmware, licensed from u-blox AG, which performs the basic GPS operation, including tracking, acquisition, navigation and position data output. For normal PVT (Position/Velocity/Time) applications, there is no need for off-chip Flash memory or ROM. The firmware supports e.g. the NMEA ® protocol (2.1 and 2.3), a binary protocol for PVT data, configuration and debugging, the RTCM protocol for DGPS, SBAS (WAAS, EGNOS and MSAS) and A-GPS (aiding) it is also possible to store the configuration settings in an optional external EEPROM. The ATR0622P1 is manufactured using Atmel®’s high-density CMOS technology. By combining the ARM7TDMI microcontroller core with on-chip SRAM, 16-channel GPS correlator, and a wide range of peripheral functions on a monolithic chip, the ATR0622P1 provides a highly flexible and cost-effective solution for GPS applications.

4973AS–GPS–12/07 ATR0622P1 2. Architectural Overview
2.1 Description
The ATR0622P1 architecture consists of two main buses, the Advanced System Bus (ASB) and the Advanced Peripheral Bus ( APB). The ASB is designed for ma ximum performance. It inter- faces the processor with the on-chip 32-bit memories. The APB is designed for accesses to on-chip peripherals and is optimized for low power consumption. The AMBA ™ Bridge provides an interface between the ASB and the APB. An on-chip Peripheral Data Controller (PDC2) transfers data between the on-chip USARTs/SPI and the on-chip and off-chip memories without processor intervention. Most importantly, the PDC2 removes the processor interrupt handling overhead and significantly reduces the number of clock cycles required for a data transfer. It can transfer up to 64K contiguous bytes without reprogramming the starting address. As a result, the performance of the microcontroller is increased and the power consumption reduced. The ATR0622P1 peripherals are designed to be easily programmable with a minimum number of instructions. Each peripheral has a 16 Kbyte address space allocated in the upper 3 Mbyte of the 4 Gbyte address space. (Except for the interrupt controller, which has 4 Kbyte address space.) The peripheral base address is the lowest address of its memory space. The peripheral register set is composed of control, mode, data, status, and interrupt registers. To maximize the efficiency of bit manipulation, frequently written registers are mapped into three memory locations. The first address is used to se t the individual register bits, the second resets the bits, and the third address reads the value stored in the register. A bit can be set or reset by writing a “1” to the corresponding position at the appropriate address. Writing a “0” has no effect. Individual bits can thus be modified without hav ing to use costly read-modify-write and complex bit-manipulation instructions. All of the external signals of the on-chip peripherals are under the control of the Parallel I/O (PIO2) Controller. The PIO2 Controller can be programmed to insert an input filter on each pin or generate an interrupt on a signal change. After reset, the user must carefully program the PIO2 Controller in order to define which peripheral signals are connected with off-chip logic. The ARM7TDMI processor operates in little-endian mode on the ATR0622P1 GPS Baseband. The processor's internal architecture and the ARM and Thumb instruction sets are described in the ARM7TDMI datasheet. The ARM standard In-Circuit Emulator (ICE) debug interface is supported via the JTAG/ICE port of the ATR0622P1. For features of the ROM firmware, refer to the software documentation available from u-blox AG, Switzerland.
