Figure 48 Timer Mode Register B2 (TMB2)
Timer mode register B2 (TMB2: $013): Two-bit read/write register that selects the timer B output
mode as shown in figure 48. It is reset to $0 by MCU reset.
Timer write register B (TWBL: $00A, TWBU: $00B): Write-only register consisting of the lower digit
(TWBL) and the upper digit (TWBU) as shown in figures 49 and 50. The lower digit is reset to $0 by
MCU reset, but the upper digit value is invalid.
Timer B is initialized by writing to timer write register B. In this case, the lower digit (TWBL) must be
written to first, but writing only to the lower digit does not change the timer B value. Timer B is
initialized to the value in timer write register B at the same time the upper digit (TWBU) is written to.
When timer write register B is written to again and if the lower digit value needs no change, writing
only to the upper digit initializes timer B.

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 51 and 52).
