Timer read register D (TRDL: $011, TRDU: $012): Read-only register consisting of a lower digit
(TRDL) and upper digit (TRDU). See figures 63 and 64. 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.
