17.3.1
Either 8-bit or 24-bit counter operation can be selected for the timer counter.
Setting 1 to the TME bit in TCR32K starts the count-up operation.
A 32K timer interrupt (32KOVI) is generated by the interrupt cycle. Table 17.1 shows
relationships between the timer counter operations according to the setting of bits EXCKSN,
CKS1, and CKS0 in TCR32K and the interrupt cycles.
