Timer mode register B2 (TMB2: $026): Two-bit write-only register that sets the input edge detection of
pin EVNB, as shown in figure 28. It is reset to $0 by an MCU reset.

Timer write register B (TWBL: $00A, TWBU: $00B): Write-only register consisting of the lower digit
(TWBL) and the upper digit (TWBU). The lower digit is reset to $0 by MCU reset, but the upper digit
value cannot be guaranteed. See figures 29 and 30.
Timer B is initialized by writing to timer write register B (TWBL: $00A, TWBU: $00B). 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.
