13 PWM & CAPTURE TIMER (T16E)

13.9 Precautions

• The prescaler must run before operating the PWM & capture timer.
• Make sure the PWM & capture timer count is halted before changing count clock settings.
• Compare data should be set with A ≥ 0 and B ≥ 1 when using the timer output. The minimum settings are A = 0
and B = 1, and the timer output cycle is half the input clock.
• Setting compare data with A > B (A > B x 2 for Fine mode) generates a compare B match signal only. It does not
generate a compare A match signal. In this case, the timer output is fixed at Low (High when INVOUT = 1).
• To prevent generating unnecessary interrupts, reset the corresponding CAIF (D0/T16E_IFLG register) or CBIF
(D1/T16E_IFLG register) before permitting compare A or compare B interrupts from CAIE (D0/T16E_IMSK
register) or CBIE (D1/T16E_IMSK register).
