Pulse-Width Modulator for Motor Control (PWMMC)
Control Logic Block
FINT4 — Fault 4 Interrupt Enable Bit
This read/write bit allows the CPU interrupt caused by faults on fault pin 4 to be
enabled. The fault protection circuitry is independent of this bit and will always
be active. If a fault is detected, the PWM pins will still be disabled according to
the disable mapping register.
1 = Fault pin 4 will cause CPU interrupts.
0 = Fault pin 4 will not cause CPU interrupts.
FMODE4 —Fault Mode Selection for Fault Pin 4 Bit
(automatic versus manual mode)
This read/write bit allows the user to select between automatic and manual
mode faults. For further descriptions of each mode, see 12.6 Fault Protection.
1 = Automatic mode
0 = Manual mode
FINT3 — Fault 3 Interrupt Enable Bit
This read/write bit allows the CPU interrupt caused by faults on fault pin 3 to be
enabled. The fault protection circuitry is independent of this bit and will always
be active. If a fault is detected, the PWM pins will still be disabled according to
the disable mapping register.
1 = Fault pin 3 will cause CPU interrupts.
0 = Fault pin 3 will not cause CPU interrupts.
FMODE3 —Fault Mode Selection for Fault Pin 3 Bit
(automatic versus manual mode)
This read/write bit allows the user to select between automatic and manual
mode faults. For further descriptions of each mode, see 12.6 Fault Protection.
1 = Automatic mode
0 = Manual mode
FINT2 — Fault 2 Interrupt Enable Bit
This read/write bit allows the CPU interrupt caused by faults on fault pin 2 to be
enabled. The fault protection circuitry is independent of this bit and will always
be active. If a fault is detected, the PWM pins will still be disabled according to
the disable mapping register.
1 = Fault pin 2 will cause CPU interrupts.
0 = Fault pin 2 will not cause CPU interrupts.
FMODE2 —Fault Mode Selection for Fault Pin 2 Bit
(automatic versus manual mode)
This read/write bit allows the user to select between automatic and manual
mode faults. For further descriptions of each mode, see 12.6 Fault Protection.
1 = Automatic mode
0 = Manual mode
