10.2.1
TSTR is an 8-bit readable/writable register that starts and stops the timer counter (TCNT) in
channels 0 to 4.
TSTR is initialized to H'E0 by a reset and in standby mode.
Bits 7 to 5—Reserved: Read-only bits, always read as 1.
Bit 4—Counter Start 4 (STR4): Starts and stops timer counter 4 (TCNT4).
Bit 3—Counter Start 3 (STR3): Starts and stops timer counter 3 (TCNT3).
Bit 2—Counter Start 2 (STR2): Starts and stops timer counter 2 (TCNT2).
