Description

PMEPOL (SIOPME Polarity). Selects the polarity of the SIOPME signal.

0: SIOPME is active low (default)

1: SIOPME is active high

PMETYPE (SIOPME Buffer Type). Selects the output buffer type of the SIOPME pin.

0: Output is open-drain and the pull-up resistor is enabled (default)

1: Output is push-pull (the pull-up resistor is disabled)

TACH2EN (FANTACH2 Multiplex Control). Selects the function connected to pin 112.

0: GPIOE07 port: GPIO (default)

1: FANTACH2: FSCM

TACH1EN (FANTACH1 Multiplex Control). Selects the function connected to pin 111.
