Figure 16. PWM Fault Report Topology
After being set HIGH, [PWM_FAULTx] FAULT_PWMx is latched even if the corresponding PWM input toggling
has recovered. The RESET_STATUS command must be issued to clear the [ANY_PWM_FAULT_FLAG] bit.
7.3.3.3 PWM Mapping
Each of the 12 output channels has a 3-bit [PWM_MAP_CH] field to assign to one PWMx input. All output
channels are assigned to PWM0 by default. Table 1 lists the mapping for each PWMx input..

7.3.3.4 PWM MAP Register Lock
To avoid unintended modification of the <PWM MAPx> registers, the <PWM MAPx> registers can be locked via
the LOCK_MAP command and unlocked via the UNLOCK_MAP command. For details, see the Register
Protection feature.
See the following addresses in Table 2: 40h through 45h, 60h, 62h, 66h through 68h, 6Ch, A0h through A3h,
A6h, and A7h.
[PWM_MAP_CH] field:
R/W. 3 bits. Mapping output channel PWM source to PWMx input.
[PWM_FAULT_MASKx] bit:
R/W. Active-high. Mask the PWM fault flag PWMx.
[PWM_MASK] bit:
R/W. Active-high. Disable the ANY_PWM_FAULT_FLAG from reporting to
ERR.
[PWM_FAULTx] bit:
R only. Active-high. HIGH: PWM monitor timer has triggered for PWMx.
[ANY_PWM_FAULT_FLAG] bit: R only. Active-high. HIGH: One or more PWMx inputs have triggered the
PWM monitor.
[SLOW_SLEW_RATE] bit:
R/W. Active-high. HIGH: Slow slew rate.
