Prescaler W can be reset by setting 1s in bits TMA3 and TMA2 of timer mode register A (TMA).
Output from prescaler W can be used to drive timer A, in which case timer A functions as a time
base for timekeeping.

Note on Oscillators
Oscillator characteristics of both the masked ROM and ZTAT™ versions are closely related to
board design and should be carefully evaluated by the user, referring to the examples shown in this
section. Oscillator circuit constants will differ depending on the oscillator element, stray
capacitance in its interconnecting circuit, and other factors. Suitable constants should be
determined in consultation with the oscillator element manufacturer. Design the circuit so that the
oscillator element never receives voltages exceeding its maximum rating.
