Figure 38 Timer Mode Register C2 (TMC2)
Timer write register C (TWCL: $00E, TWCU: $00F): Write-only register consisting of a lower digit
(TWCL) and an upper digit (TWCU) as shown in figures 39 and 40. The lower digit is reset to $0 by
MCU reset, but the upper digit value is invalid.
Timer C is initialized by writing to timer write register C (TWCL: $00E, TWCU: $00F). In this case,
the lower digit (TWCL) must be written to first, but writing only to the lower digit does not change the
timer C value. Timer C is initialized to the value in timer write register C at the same time the upper
digit (TWCU) is written to. When timer write register C is written to again and if the lower digit value
needs no change, writing only to the upper digit initializes timer C.
