9.7.1.3 Manual Mode
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
In manual mode, the PWM(s) are disabled immediately once a filtered
fault condition is detected (logic high). The PWM(s) remain disabled until
software clears the corresponding FFLAGx event bit and a new PWM
cycle begins. In manual mode, the fault pins are grouped in pairs, each
pair sharing common functionality. A fault condition on fault 1 may be
cleared, allowing the PWM(s) to enable at the start of a PWM cycle
regardless of the logic level at the fault pin. See
condition on fault 4 can be cleared, allowing the PWM(s) to enable, only
if a logic low level at the fault pin is present at the start of a PWM cycle.
