DATASHEET
The Fan Interrupt Enable Register controls the masking for errors generated by the Fan Driver. When
a channel is masked, it will not cause the ALERT pin to be asserted when an error condition is
detected.
Bit 1 - SPIN_INT_EN - Allows the FAN_SPIN bit to assert the ALERT pin.
‘0’ (default) - the FAN_SPIN bit will not assert the ALERT pin though it will still update the Status
Register normally.
‘1’ - the FAN_SPIN bit will assert the ALERT pin.
Bit 0 - STALL_INT_EN - Allows the FAN_STALL bit or DRIVE_FAIL bit to assert the ALERT pin.
‘0’ (default) - the FAN_STALL bit or DRIVE_FAIL bit will not assert the ALERT pin though will still
update the Status Register normally.
‘1’ - the FAN_STALL bit will assert the ALERT pin.
6.17
PWM Configuration Register
The PWM Config Register controls the output type and polarity of the PWM output.
Bit 4 - PWM_OT - Determines the output type for the PWM pin.
‘0’ (default) - The PWM pin is configured as an open drain output.
‘1’ - The PWM pin is configured as a push-pull output.
Bit 0 - POLARITY1 - Determines the polarity of PWM1 (if enabled).
‘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.
6.18
PWM Base Frequency Register
The PWM Base Frequency Register controls base frequency of the PWM output.
Bits 1-0 - PWM_BASE[1:0] - Determines the base frequency of the PWM driver (PWM).
