9.11.7 PWM Disable Mapping Write-Once Register
This write-once register holds an 8-bit value which determines which
PWM pins will be disabled if an external fault or software disable occur.
For a further description of the disable mapping, see 9.7 Fault
Protection. After this register is written for the first time, it cannot be
rewritten unless a RESET occurs.

FMODE1 — Fault Mode Selection for Fault Pin 1 (Automatic versus
Manual Mode)
This read/write bit allows the user to select between automatic and
manual mode faults. For further description of each mode, see 9.7
Fault Protection.
1 = Automatic mode
0 = Manual mode
