SIO3ES1: SIO Ch.3 receive error/TM16 Ch.3 compare A interrupt factor switching (D5) / Interrupt factor TM16 function switching register (0x402CB)
Switches the interrupt factor.
Write "1": SIO Ch.3 receive error
Write "0": TM16 Ch.3 compare A
Read: Valid
Set to "1" to use the SIO Ch.3 receive error interrupt.

Remove write protection for the TTBR register.
Write 0x59: Write protection is removed
Write not the above: No operation (write protected)
Read: Valid
Before writing to the TTBR register, set TBRP to "0x59" to remove the write protection. Then when data is written to the most significant byte (0x48137) of the TTBR, the register once again becomes
After an initial reset, TBRP is set to "0x0" (write protected).
