Figure 18-36 Hall Mode Flag Logic
Please note that for flags CHE, WHE, and STR, the interrupt request generation is
triggered by the set signal for the flag. That means, a request can be generated even if
the flag is already set. There is no need to reset the flag in order to enable further
interrupt requests.
The implementation for the IDLE flag is different. It is set by HW through signal CM_WHE
if enabled by bit ENIDLE. Software can also set the flag via bit SIDLE. As long as bit IDLE
is set, the modulation pattern field MCMP is cleared to force the outputs to the passive
state. Flag IDLE must be reset by software through bit RIDLE in order to return to normal
operation. To fully restart from IDLE mode, the transfer requests for the bitfields in
register MCMOUTS to register MCMOUT have to be initiated by software via bits
STRMCM and STRHP in register MCMOUTS. In this way, the release from IDLE mode
is under software control, but can be performed synchronously to the PWM signal.
