SPI_CS0_B

O

CMOS_V3P3

1

V3P3A

This signal is the SPI Chip 

Select 0 output.

SPI_CS1_B/

GPIO_SUS12

O

CMOS_V3P3

1

V3P3A

This signal is the SPI Chip 

Select 1 output. If the 

SPI_CS1_B interface is not 

used, the signal can be used 

as GPIO SUS Port 15.

SPI_MISO

I

CMOS_V3P3

1

20K, PU

V3P3A

Data input from the SPI to the 

SoC. This signal has a weak 

internal pull-up that is always 

ON except during leakage test 

mode.

SPI_MOSI

I/O

CMOS_V3P3

1

20K, PD

V3P3A

Data output from the SoC to 

the SPI.

SPI_CLK

O

CMOS_V3P3

1

V3P3A

SPI clock signal. The default is 

20 MHz, but can be set to 

33 MHz. During bus idle, the 

SoC drives the clock signal 

low.
