Pin Description

SS[2:0]

O5/4m

41, 40, 34

SPI Slave Select for SPI master.

SS[2:0] is a tri-stateable output, which requires an external pull-up resistor.

SCLK

O5/4m

SPI CLocK for SPI master.

SCLK is a tri-stateable output. At Mode 0 or 2, SCLK requires external pull-down

resistor; while at Mode 1 or 3, SCLK requires external pull-up resistor.

MOSI

O5/4m

SPI Master Output Slave Input line for SPI master.

When High Speed SPI controller is operating in master module, MOSI is used to

transmit serial data and is a tri-stateable output.

MISO

SPI Master Input Slave Output line for SPI master.

When High Speed SPI controller is operating in master module, MISO is used to

receive serial data.

SWAKEn

I5/PU

SPI External Wakeup

SWAKEn is external wakeup for SPI interface.

GPIO16

B5/8m

General Purpose I/O signal

Note: Above signals are only valid when CHIP_MODE = 100 and 110.
