RXD0 Received data Input Received data input pin for serial I/O channel 0.
TXD1 Transmit data Output Transmit data output pin for serial I/O channel 1.
RXD1 Received data Input Received data input pin for serial I/O channel 1.
TXD2 Transmit data Output Transmit data output pin for serial I/O channel 2.
RXD2 Received data Input Received data input pin for serial I/O channel 2.
TXD3 Transmit data Output Transmit data output pin for serial I/O channel 3.
RXD3 Received data Input Received data input pin for serial I/O channel 3.
TXD4 Transmit data Output Transmit data output pin for serial I/O channel 4.
RXD4 Received data Input Received data input pin for serial I/O channel 4.
TXD5 Transmit data Output Transmit data output pin for serial I/O channel 5.
RXD5 Received data Input Received data input pin for serial I/O channel 5.
Real-time RTDTXD RTD transmit data Output Serial data output pin for the real-time debugger.
debugger RTDRXD RTD received data Input Serial data input pin for the real-time debugger.
(RTD) RTDCLK RTD clock input Input Serial data transmit/receive clock input pin for the real-time
debugger.
RTDACK RTD acknowledge Output A low-level pulse is output from this pin synchronously with
the start clock for the real-time debugger’s serial data output
word. The low-level pulse width indicates the type of command/
data received by the real-time debugger.
CAN CTX0, CTX1 Transmit data Output This pin outputs data from the CAN module.
CRX0, CRX1 Received data Input This pin accepts as input the data for the CAN module.
JTAG JTMS Test mode select Input Test mode select input to control the state transition of the
test circuit.
JTCK Test clock Input Clock input for the debug module and test circuit.
JTRST Test reset Input Test reset input to initialize the test circuit asynchronously
with device operation.
JTDI Test data input Input This pin accepts as input the test instruction code or test data
that is serially received.
JTDO Test data output Output This pin outputs the test instruction code or test data serially.
