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 GPIOE07/FANTACH2.

0: GPIOE07 port: GPIO (default)

1: FANTACH2: Health Management

For correct selection of the GPIO on this pin, also see Table 3 on page 18.

TACH1EN (FANTACH1 Multiplex Control). Selects the function connected to pin GPIOE06/FANTACH1.

0: GPIOE06 port: GPIO (default)

1: FANTACH1: Health Management

For correct selection of the GPIO on this pin, also see Table 3 on page 18.

Reserved.

TACH4EN (FANTACH4 Multiplex Control). Selects the function connected to the GPIOE02/FANTACH4 pin.

0: GPIOE02 port: GPIO (default)

1: FANTACH4: Health Management

For correct selection of the GPIO on this pin, also see Table 3 on page 18.

TACH3EN (FANTACH3 Multiplex Control). Selects the function connected to the GPIOE01/FANTACH3 pin.

0: GPIOE01 port: GPIO (default)

1: FANTACH3: Health Management

For correct selection of the GPIO on this pin, also see Table 3 on page 18.

GPIO03EN (GPIOE10-GPIOE13 Multiplex Control). Selects the functions connected to pins 113-116.

0: 5V_DDCSDA, 5V_DDCSCL, CC_DDCSDA, CC_DDCSCL: Glue Functions (default)

1: GPIOE10-GPIOE13 ports: GPIO

For correct selection of GPIOs on these pins, also see Table 3 on page 18.
