Timer write register B (upper digit) (TWBU: $00B)
Figure 36 Timer Write Register B Upper Digit (TWBU)
Timer read register B (TRBL: $00A, TRBU: $00B): Read-only register consisting of the lower digit
(TRBL) and the upper digit (TRBU) that holds the count of the timer B upper digit (figures 37 and 38).
The upper digit (TRBU) must be read first. At this time, the count of the timer B upper digit is obtained,
and the count of the timer B lower digit is latched to the lower digit (TRBL). After this, by reading
TRBL, the count of timer B when TRBU is read can be obtained.
When the input capture timer operation is selected and if the count of timer B is read after a trigger is
input, either the lower or upper digit can be read first.
