Function
Receive Data
Serial receive data input to the SCCs. (I)
Transmit Data
Serial transmit data output from the SCCs. (O)
Request to send outputs indicate that the SCC is ready to
transmit data. (O)
Request to Send
Clear to Send
Carrier Detect
RTS4-RTS1
CTS4-CTS1
CD4-CD1
Clear to send inputs indicate to the SCC that data
transmission may begin. (I)
Carrier detect inputs indicate that the SCC should begin
reception of data. (I)
SCC
This output from SCC1 identifies the start of a receive frame.
Can be used by an Ethernet CAM to perform address
matching. (O)
Receive Start
RSTRT1
RRJCT1
This input to SCC1 allows a CAM to reject the current
Ethernet frame after it determines the frame address did not
match. (I)
Receive Reject
Input clocks to the SCCs, SCMs, SI, and the baud rate
generators. (I)
Clocks
CLK8-CLK1
DREQ2-DREQ1
DACK2-DACK1
DONE2-DONE1
TGATE2-TGATE1
TIN4-TIN1
A request (input) to an IDMA channel to start an IDMA
transfer. (I)
DMA Request
DMA Acknowledge
DMA Done
An acknowledgement (output) by the IDMA that an IDMA
transfer is in progress. (O)
IDMA
A bidirectional signal that indicates the last IDMA transfer in
a block of data. (I/O)
An input to a timer that enables/disables the counting
function. (I)
Timer Gate
Time reference input to the timer that allows it to function as
a counter. (I)
TIMER
Timer Input
Output waveform (pulse or toggle) from the timer as a result
of a reference value being reached. (O)
Timer Output
SPI Master In Slave Out
SPI Master Out Slave In
SPI Clock
TOUT4-TOUT1
SPIMISO
Serial data input to the SPI master (I); serial data output from
an SPI slave. (O)
Serial data output from the SPI master (O); serial data input
to an SPI slave. (I)
SPIMOSI
SPI
Output clock from the SPI master (O); input clock to the SPI
slave. (I)
SPICLK
SPI Select
SPISEL
SPI slave select input. (I)
