Description
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.
