Timer write register C (upper digit) (TWCU: $00F)
Figure 46 Timer Write Register C Upper Digit (TWCU)
Timer read register C (TRCL: $00E, TRCU: $00F):
Timer read register C (TRCL: $00E, TRCU: $00F)
is a read-only register composed of a lower digit (TRCL: $00E), and an upper digit (TRCU: $00F) from
which the value of the upper digit of timer C is read directly.
First, read the upper digit (TRCU) of timer read register C. The current value of the timer C upper digit is
read and, at the same time, the value of the timer C lower digit is latched in the lower digit (TRCL) of timer
read register C. The timer C value is obtained when the upper digit (TRCU) of timer read register C is read
by reading the lower digit (TRCL) of timer read register C.
