Real-Time
RTDTXD
Transmit data
Output
Serial data output pin of the real-time debugger
Debugger
RTDRXD
Receive data
Input
Serial data input pin of the real-time debugger
RTDCLK
Clock input
Input
Serial data transmit/receive clock input pin of the real-time debugger
RTDACK
Acknowledge
Output
This pin outputs a low pulse synchronously with the real-time debugger’s
first clock of serial data output word. The low pulse width indicates the
type of the command/data the realtime debugger has received.
Flash-
FP
Flash protect
Input
This pin protects the flash memory against E/W in hardware.
only
CAN
CTX
Transmit data
Output
Data output pin from CAN module.
CRX
Receive data
Input
Data input pin to CAN module.
JTAG
JTMS
Test mode
Input
Test select input for controlling the test circuit’s state transition
JTCK
