Note:
17.2.2
The timer counter is a 24-bit counter for which either 8- or 24-bit operation is selectable.
Allocation to the registers of the timer counter differs according to the setting of the EXCKSN bit
in TCR32K.
(1)
The timer counter operates as an 8-bit counter. Only TCNT32K1 is used and TCNT32K2 and
TCNT32K3 become reserved registers. Clearing the TME bit in the timer control register
(TCR32K) initializes TCNT32K1 to H'00.

Description
When this bit is set to 1, TCNT32K starts counting. When
this bit is cleared, TCNT32K stops counting and is
initialized to H'00_00_00.
Reserved
These bits are always read as 1 and cannot be modified.
