Notes: 1. Includes switching from low to stop, and from stop to low.
12.8.6
If module stop mode is entered when an interrupt has been requested, it will not be possible to
clear the CPU interrupt source or the DTC activation source. Interrupts should therefore be
disabled before entering module stop mode.
12.8.7
When the 16-bit count mode and the compare-match count mode are set at the same time, input
clocks for TCNT_0 and TCNT_1 (TCNT_2 and TCNT_3) * are not generated and the timer stops
incrementation. This setting is prohibited.
Note: * Not available in the H8S/2237 Group and H8S/2227 Group.
