HD404829R Series
• 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.
• Port mode register C (PMRC: $025): Write-only register that selects R2₀/EVND pin function as shown
in figure 53. It is reset to $0 by MCU reset.
• Detection edge select register 2 (ESR2: $027): Write-only register that selects the detection edge of
signals input to pin EVND as shown in figure 69. It is reset to $0 by MCU reset.
