14.2.2
TCSR is an 8-bit readable/writable * register. Its functions include selecting the clock source to be
input to TCNT, and the timer mode.
TCR is initialized to H'00 by a reset and in hardware standby mode. It is not initialized in software
standby mode.
Note: * TCSR is write-protected by a password to prevent accidental overwriting. For details
