• Manufacturer Part Number: h8s-2111b
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family / H8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

Notes: 1. Includes switching from low to stop, and from stop to low.
10.10.6 Mode Setting with Cascaded Connection
If the 16-bit count mode and compare-match count mode are set simultaneously, the input clock
pulses for TCNT_0 and TCNT_1, and TCNT_X and TCNT_Y and TCNT_A and TCNT_B are
not generated, and thus the counters will stop operating. Simultaneous setting of these two modes
should therefore be avoided.
10.10.7 Module Stop Mode Setting
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 20, Power-Down Modes.
