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 63. 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.

Figure 63 Timer Mode Register D1 (TMD1)
Timer mode register D2 (TMD2: $015): Four-bit read/write register that selects the timer D output
mode and input capture operation as shown in figure 64. It is reset to $0 by MCU reset.
Timer write register D (TWDL: $011, TWDU: $012): Write-only register consisting of the lower digit
(TWDL) and the upper digit (TWDU). The operation of timer write register D is basically the same as
that of timer write register B (TWBL: $00A, TWBU: $00B).
Timer read register D (TRDL: $011, TRDU: $012): Read-only register consisting of the lower digit
(TRDL) and the upper digit (TRDU). The operation of timer read register D is basically the same as
that of timer read register B (TRBL: $00A, TRBU: $00B).
When the input capture timer operation is selected and if the count of timer D is read after a trigger is
input, either the lower or upper digit can be read first.
