Bit 2 - STALL_INT_EN2 - Allows the FAN_STALL2 bit or DRIVE_FAIL2 bit to assert the ALERT# pin.
Bit 1 - SPIN_INT_EN1 - Allows the FAN_SPIN1 bit to assert the ALERT# pin.
Bit 0 - STALL_INT_EN1 - Allows the FAN_STALL1 bit or DRIVE_FAIL1 bit to assert the ALERT# pin.
The PWM Config Register controls the output type and polarity of all PWM outputs.
Bit 3 - POLARITY4 - Determines the polarity of PWM4 (if enabled).
Bit 2 - POLARITY3 - Determines the polarity of PWM3 (if enabled).
Bit 1 - POLARITY2 - Determines the polarity of PWM2 (if enabled).
Bit 0 - POLARITY1 - Determines the polarity of PWM1 (if enabled).
The PWM Base Frequency Register determines the base frequency that is used with the PWM Divide
register to determine the final PWM frequency. Each PWM driver uses the same divide ratio as set by
the PWM Divide Register.

‘0’ (default) - the FAN_STALL2 bit or DRIVE_FAIL2 bit will not assert the ALERT# pin though it will
still update the Status Register normally.
‘1’ - the FAN_STALL 2 or DRIVE_FAIL2 bits will assert the ALERT# pin if set.
‘0’ (default) - the FAN_SPIN1 bit will not assert the ALERT# pin though it will still update the Status
Register normally.
‘1’ - the FAN_SPIN1 bit will assert the ALERT# pin.
‘0’ (default) - the FAN_STALL1 bit or DRIVE_FAIL1 bit will not assert the ALERT# pin though will
still update the Status Register normally.
‘1’ - the FAN_STALL1 or DRIVE_FAIL1 bit will assert the ALERT# pin if set.
‘0’ (default) - the Polarity of the PWM driver is normal. A drive setting of 00h will cause the output
to be set at 0% duty cycle and a drive setting of FFh will cause the output to be set at 100% duty
cycle.
‘1’ - The Polarity of the PWM driver is inverted. A drive setting of 00h will cause the output to be
set at 100% duty cycle and a drive setting of FFh will cause the output to be set at 0% duty cycle.
