KIT33905 Evaluation Boards , Rev. 2.0
10 Freescale Semiconductor
Hardware Configuration
6.6 Connector J2 – SPI Control
6.7 EVB – KITUSBSPIDGLEVME Interconnection
Pin # Pin Name Description
1 TXDC CAN bus transmit data input. Internal pull-up to VDD
2 CSB Chip select pin for the SPI. When the CS is low, the device is selected. In Low
Power mode with VDD ON, a transition on CS is a wake-up condition
3 INTB This output is asserted low when an enabled interrupt condition occurs. The out-
put is a push-pull structure.
4 MISO SPI data sent to the MCU. When the CS is high, MISO is high-impedance
5 RSTB This is the device reset output whose main function is to reset the MCU. It has an
internal pull-up to VDD. The reset input voltage is also monitored in order to detect
external reset and safe conditions
6 MOSI SPI data received by the device
7 NC No Connect
8 SCLK Clock input for the Serial Peripheral Interface (SPI) of the device
9 NC No Connect
10 NC No Connect
11 I_WAKE Active high input to enable on-board FET to create a 5.0 mA load on VDD
12 NC No Connect
13 NC No Connect
14 NC No Connect
15 NC No Connect
16 GND Ground termination
