The two 8-bit pulse accumulators PAC1 and PAC0 are cascaded to form
the PACB 16-bit pulse accumulator. When PACB in enabled, (PBEN=1
in PBCTL, $B0) the PACN1 and PACN0 registers contents are
respectively the high and low byte of the PACB.
When PACN1 overflows from $FF to $00, the Interrupt flag PBOVF in
PBFLG ($B1) is set.
Full count register access should take place in one clock cycle. A
separate read/write for high byte and low byte will give a different result
than accessing them as a word.
Read or write any time.
MCZI — Modulus Counter Underflow Interrupt Enable
MODMC — Modulus Mode Enable
For proper operation, the MCEN bit should be cleared before modifying
the MODMC bit in order to reset the modulus counter to $FF.
