Figure 53 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 54 and 55. The operation of timer write
register C is basically the same as that of timer write register B (TWBL: $00A, TWBU: $00B).
