    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.
