• Manufacturer Part Number: r4f2426
• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2400 Series
• Manufacturer: Renesas Electronics Corporation.

Notes: 1. Includes switching from low to stop, and from stop to low.
13.8.6
If 16-bit counter mode and compare match count mode are specified at the same time, input clocks
for TCNT_0 and TCNT_1 are not generated, and the counter stops. Do not specify 16-bit counter
and compare match count modes simultaneously.
13.8.7
Operation of the TMR can be disabled or enabled using the module stop control register. The
initial setting is for operation of the TMR to be halted. Register access is enabled by clearing
module stop mode. For details, refer to section 24, Power-Down Modes.
13.8.8
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 and DMAC activation source. Interrupts should
therefore be disabled before entering module stop mode.
