• Port registers when CSIF3 is used
When CSIF3 is used for communication, port registers are set to make the SIF3, SOF3, SCKF3, and HS (P913)
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.)

2. 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.
