Registers for Timer D Operation:
By using the following registers, timer D operation modes are selected
and the timer D count is read and written.
Timer mode register D1 (TMD1: $010)
Timer mode register D2 (TMD2: $015)
Timer write register D (TWDL: $011, TWDU: $012)
Timer read register D (TRDL: $011, TRDU: $012)
Port mode register C (PMRC: $025)
Detection edge select register 2 (ESR2: $027)
Timer mode register D1 (TMD1: $010): Four-bit write-only register that selects the free-
running/reload timer function, input clock source, and the prescaler division ratio as shown in figure 41.
It is reset to $0 by MCU reset.
Writing to this register is valid from the second instruction execution cycle after the execution of the
previous timer mode register D1 (TMD1: $010) write instruction. Setting timer D’s initialization by
writing to timer write register D (TWDL: $011, TWDU: $012) must be done after a mode change
becomes valid.
When selecting the input capture timer operation, select the internal clock as the input clock source.
