Timer write register D (upper digit) (TWDU: $012)
Figure 53 Timer Write Register D Upper Digit (TWDU)
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 registerC (TRCL: $00E, TRCU: $00F).
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.
