Timer write register C (upper digit) (TWCU: $00F)
Figure 37 Timer Write Register C Upper Digit (TWCU)
Timer read register C (TRCL: $00E, TRCU: $00F): Read-only register consisting of a lower digit
(TRCL) and an upper digit (TRCU) that holds the count of the timer C upper digit as shown in figures
38 and 39. The upper digit (TRCU) must be read first. At this time, the count of the timer C upper digit
is obtained, and the count of the timer C lower digit is latched to the lower digit (TRCL). After this, by
reading TRCL, the count of timer C when TRCU is read can be obtained.
