10.1 SDIO Pin Description
The RK903 supports SDIO version 2.0 for both 1-bit (25 Mbps), 4-bi t modes (100 Mbps), and high speed 4-bit (50 MHz clocks – 200 Mbps). It has the abi lity to stop the SDIO clock and map the interrupt signal into a GPIO pin. This ‘out-of-band’ interrupt signal notifies the host when the WLAN device wants to turn on t he SDIO interface. The ability to force the control of the gated clocks from within the WLAN chip is also provided. Function 0 Standard SDIO function (Max BlockSize / ByteCount = 32B) Function 1 Backplane Function to acce ss the internal System On Chip (SOC) address space (Max BlockSize / ByteCount = 64B) Function 2 WLAN Function for efficient WLAN packet transfer through DMA (Max BlockSize/ByteCount=512B) SDIO Pin Description SD 4-Bit Mode SD 1- Bit Mode g-SPI Mode DATA0 Data Line 0 DATA Data Line DO Data Output DATA1 Data Line 1 or Interrupt IRQ Interrupt IRQ Interrupt DATA2 Data Line 2 or Read Wait RW Read Wait NC Not Used DATA3 Data Line 3 NC Not Used CS Card Select

11.1 Power-up Sequence Timing Diagram
The RK903 has three signals t hat allow the host to control power consumption by enabling or disabling the Bluetooth, WLAN and internal regulator blocks. These signals are described below. Additionally, diagrams are provided to indica te proper sequencing of the signals for carious operating states. The timing value indicated are minimum required values: longer delays are also acceptable. Note that the WL_REG_ON and BT_REG_ON are ORed in the RK903. The diagrams show both signals going high at the same time (as would be the case if both REG signals were controlled by a single host GPIO). If two independent hos t GPIOs are used (on for WL_REG_ON and one for BT_REG_ON), then only one of the two signals needs to be high to enable the RK903 regulators. ※ WL_REG_ON: Used by the PMU to power up the WLAN section. It is also OR-gated with the BT_REG_ON input to control the internal BCM4330 regulators. When this pin is high, the regulators are enabled and the WLAN section is out of reset. When this pin is low the WLAN section is in reset. A “warm” WLAN reset can be initiated by driving WL_REG_ON low fo r at least 10 microseconds. If both the BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled. ※ BT_REG_ON: Used by the PMU (OR-gated with WL_REG_ON) to power up the internal RK903 regulators. If both the BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled. ※ BT_RST_N: Low asserting reset for Bluetoot h and FM only. This pin has no effect on WLAN and does not control any PMU functions. This pin must be driven high or low (not left floating).
