// Register: LGPT1_O_FAULT
//
//*****************************************************************************
// Field:   [1:0] CTL
//
// Fault control
//
// On active fault input the counter can optionally stop. If the counter stops
// this is done by hardware, software must then restart the timer if wanted.
// The fault input overrides channel 0 IOC input when CTL != DIS.
// This means that channel 0 receives fault as input signal when C0CFG.INPUT =
// IO and CTL != DIS.
//
// CHFILT can be used to avoid glitching on the fault input. Fault is level
// triggered, the polarity is set by the C0CFG.EDGE field. Here  C0CFG.EDGE =
// RISE gives active high and C0CFG.EDGE = FALL gives active low polarity.
//
// Fault is typically used together with PARK to stop the PWM signal to an
// external motor control circuit safely. Configure PARK to ensure predefined
// values of the PWM outputs.
//
// If CTL != DIS the RIS.FAULT interrupt is set immediately when the fault
// input is active while CTL.MODE != DIS.
//
// The three modes of fault is described below:
//
// CTL = IMMEDIATE
// In this mode the counter stops immediately on an active fault input. This is
// done by hardware by setting CTL.MODE = DIS. To start the counter software
// must set CTL.MODE != DIS.
// When the counter has stopped, the input synchronizers and the channel filter
// is not running. This means that if RIS.FAULT is cleared it will not be set
// again while CTL.MODE = DIS.
//
// CTL = ZEROCOND
// In this mode the counter stops when CNTR = 0 after an active fault input. If
// the RIS.FAULT interrupt has been cleared by software before CNTR = 0, and
// the fault input is inactive, the counter will continue as normal.
// When the counter stops on zero, it can be started again by clearing the
// RIS.FAULT interrupt if the fault input is inactive. To change the counter
// mode set CTL.MODE = DIS, clear the RIS.FAULT interrupt, then start timer in
// wanted mode.
//
// CTL = IRQ
// In this mode only the RIS.FAULT flag is set on an active fault input.
// ENUMs:
// IRQ                      Interrupt request. Only set RIS.FAULT on active
//                          fault.
// ZERCOND                  Zero condition. The counter stops when CNTR = 0.
// IMMEDIATE                Immediate reaction. The counter stops immediately
//                          on fault.
// DIS                      Disable. The timer ignores fault.
