Pin Name Pin # Pin Description Type Remark

Master Slave

SPI-MISO J701, 8 Master In Slave Out In Out SPI Bus data line in the direction of

slave to master.

SPI-MOSI J701, 7 Master Out Slave In Out In SPI Bus data line in the direction of

master to slave.

SPI-SCLK J701, 6 Serial Clock Out In SPI Bus clock driven by master.

Depending on how polarity and phase

are configured, this clock’s edges

indicate when the data on MISO and

MOSI are valid.

SPI-MRQ J703, 6 Master Request Out In Driven by the master to indicate to

slave that SPI activity needs to take

place. If the slave is sleeping, this signal

will wake it up. When the slave detects

this signal high, it must respond by

driving Slave Ready high.

SPI-SRDY J703, 7 Slave Ready In Out Driven by the slave to indicate to the

master that it is awake and ready to

perform SPI Bus transactions.

SPI-SRQ J703, 8 Slave Request In Out Driven by the slave to indicate that it

wishes to send a message over SPI Bus

to the master. This is necessary since

master drives the clock and this gives

the slave a way to inform the master

that the slave wishes the clock to be

driven.

SPI-CS0 J701, 5 SPI Chip Select Out In Used by Master to select which slave it

is communicating with over SPI Bus

RXD0 J701, 1 Serial 0 Receive Out In Reserved for future use.

TXD0 J701, 2 Serial 0 Transmit In Out Reserved for future use.

T_OUT J701, 3 TBD

RESET J701, 4 eNode Reset Out In Provides Host with ability to reset the
