Pulse-Width Modulator for Motor Control
9.12.10 Fault Acknowledge Register
Technical Data
182
FFLAG4 — Fault Event Flag 4
FPIN4 — State of Fault Pin 4 Bit
The fault acknowledge register (FTACK) is used to acknowledge and
clear the FFLAGs. In addition, it is used to monitor the current sensing
bits to test proper operation.

Pulse-Width Modulator for Motor Control (PWMMC)
The FFLAG4 event bit is set within two CPU cycles after a rising edge
on fault pin 4. To clear the FFLAG4 bit, the user must write a 1 to the
FTACK4 bit in the fault acknowledge register.
This read-only bit allows the user to read the current state of fault
pin 4.
Ad-
1 = A fault has occurred on fault pin 4
0 = No new fault on fault pin 4
1 = Fault pin 4 is at logic 1.
0 = Fault pin 4 is at logic 0.
