• Port registers when UARTA0 is used
When UARTA0 is used, port registers are set to make the TXDA0 and RXDA0 pins valid by the debug monitor
program. Do not change the following register settings with the user program during debugging. (The same
value can be overwritten.)

• Port registers when CSIB0 is used
When CSIB0 is used, port registers are set to make the SIB0, SOB0, SCKB0, and HS (PMC0) pins valid by the
debug monitor program. Do not change the following register settings with the user program during debugging.
(The same value can be overwritten.)

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 perform port register settings in 8-bit units, the user program can
usually use read-modify-write. If an interrupt for debugging occurs before writing, however, an
unexpected operation may be performed.
