CHAPTER 31 ON-CHIP DEBUG FUNCTION
• Port registers when UARTA0 is used
When UARTA0 is used, port registers are set by the debug monitor program to make the TXDA0 and
RXDA0 pins valid. Do not change the following register settings in the user program during debugging.
(The same value can be written again.)

• Port registers when CSIB0 is used
When CSIB0 is used, port registers are set by the debug monitor program to make the SIB0, SOB0, SCKB0,
and HS (PCM0) pins valid. Do not change the following register settings in the user program during
debugging. (The same value can be written again.)

Note
Note
Writing to this bit is prohibited.
The port values corresponding to the HS pin are changed by the monitor program according to
the debugger status. To specify port register settings in 8-bit units, read-modify-write can
usually be used in the user program. If an interrupt for debugging occurs before writing,
however, an unexpected operation may be performed.
