TCSR_0: Timer control/status register_0
TCNT_0: Timer counter_0
TCSR_1: Timer control/status register_1
TCNT_1: Timer counter_1
Notes: 1. The internal reset signal first resets the WDT in which the overflow has occurred first.
2. The internal NMI interrupt signal can be independently output from either WDT_0 or WDT_1.
The interrupt controller does not distinguish the NMI interrupt request from WDT_0 from
that from WDT_1.
