4-2 PME _PIN_SEL

R/W

These registers use to select PME# pin clock output function.

000: PME# pin will use as normal function.

001: PME# pin will output 100HZ or 50HZ clock (select by CR00 bit4)

010: When PWM duty over LIMIT 2, PME# pin will output 100HZ or 50HZ

clock.

011: When PWM duty under Limit1, PME# pin will output 100HZ or 50HZ clock

100~111: When PWM duty over or under LIMIT3/0, PME# pin will output 1HZ

clock

1-0 TURBO_PIN_SEL

R/W

These registers use to select Turbo# pin clock output function.

00: Turbo pin will use as normal function.

01: Turbo pin will output 100HZ or 50HZ clock (select by CR00 bit4)

10: When PWM duty over LIMIT2, Turbo pin will output 100HZ or 50HZ clock.

11: When PWM duty under LIMIT1, Turbo pin will output 100HZ or 50HZ clock
