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.
