Description

XIRQMUX (XIRQ Multiplex Control). Selects the function connected to pin 10.

0: GPIO06 port - GPIO (default; internally, XIRQ is set to 0; Interrupt not active)

1: XIRQ - X-Bus (PC87416 and PC87417)

XSTB2MUX (XSTB2 Multiplex Control). Selects the function connected to pin 32. The default value is set to 0

if XCNF2 = 1 or to 1 if XCNF2 = 0. The XCNF2 strap is sampled at VSB Power-Up reset.

0: XSTB2 - X-Bus (PC87416 and PC87417)

1: GPO60 port - GPIO

XSTB1MUX (XSTB1 Multiplex Control). Selects the function connected to pin 33. The default value is set to 0

if XCNF2 = 1 or to 1 if XCNF2 = 0. The XCNF2 strap is sampled at VSB Power-Up reset.

0: XSTB1 - X-Bus (PC87416 and PC87417)

1: GPO61 port - GPIO

XSTB0MUX (XSTB0 Multiplex Control). Selects the function connected to pin 34. The default value is set to 0

if XCNF2 = 1 or to 1 if XCNF2 = 0. The XCNF2 strap is sampled at VSB Power-Up reset.

0: XSTB0 - X-Bus (PC87416 and PC87417)

1: GPO62 port - GPIO

XCS3MUX (XCS3 Multiplex Control). Selects the function connected to pin 20.

0: GPIOE40 port - GPIO (default)

1: XCS3 - X-Bus (PC87416 and PC87417)

XCS2MUX (XCS2 Multiplex Control). Selects the function connected to pin 21.

0: GPIOE41 port - GPIO (default)

1: XCS2 - X-Bus (PC87416 and PC87417)

XCS1MUX (XCS1 Multiplex Control). Selects the function connected to pin 22.

0: GPIO26 port - GPIO (default)

1: XCS1 - X-Bus (PC87416 and PC87417)

XCS0MUX (XCS0 Multiplex Control). Selects the function connected to pin 23. The default value is set to 0 if

XCNF2 = 1 or to 1 if XCNF2 = 0. The XCNF2 strap is sampled at VSB Power-Up reset.

0: XCS0 - X-Bus (PC87416 and PC87417)

1: GPIO27 port - GPIO
