• Manufacturer: RENESAS [Renesas Technology Corp]

Notes: 1. Includes switching from low to stop, and from stop to low.
12.9.6
If the 16-bit count mode and compare-match count mode are set simultaneously, the input clock
pulses for TCNT_0 and TCNT_1 are not generated, and thus the counters will stop operating.
Simultaneous setting of these two modes should therefore be avoided.
12.9.7
TMR operation can be enabled or disabled using the module stop control register. The initial
setting is for TMR operation to be halted. Register access is enabled by canceling the module stop
mode. For details, refer to section 26, Power-Down Modes.
