FG watchdog
The FG watchdog monitors FGOUT output, allowing an internal timer to count until a transition in FGOUT occurs
and clears the counter. Should timer time-out occur by reaching a count equivalent to 25 ms (512 counts of the
PWM clock), two actions are taken: 1) speed discriminator UP error output is set to 100%; 2) lock detect is set
and lock timer begins counting (see lock timer oscillator/counter section). These actions ensure the digital
integrator counts up (increasing motor drive PWM) at startup of the system, or, if the FG signal is lost during
operation and if no detection of an FG period of < 25 ms occurs for the duration of the lock timer, the IC will go
into shutdown mode, disabling the motor drive (see shutdown section).
