Bit 7: Set to 1 , select pin 9 SMI#/PWMOUT2 as PWM output. Set to 0, select pin 9 as SMI# output.
Bit6: Set to 1, the SMI# output type of temperature sensor 1 is set to Comparator Interrupt mode. Set
to 0, the SMI# output type is set to Interrupt mode (defined by CR[4Ch] Bit 5 ).
Bit 5: Set to 1, the SMI# output type of temperature sensor 1 is set to One-Time interrupt mode. Set
to 0, the SMI# output type of temperature sensor 1 is set to Two-Times interrupt mode.
Bit 4 : Reserved. User Defined.
Bit 3: Disable temperature sensor 1 over-temperature (OVT) output if set to 1. Default 0, enable
OVT1 output through pin OVT#.
Bit 2: Over-temperature polarity. Write 1, OVT# active high. Write 0, OVT# active low. Default 0.
Bit 1-0: Reserved. User Defined.
