When PINMMR9[0] = 1, GIOA[5] is connected directly to N2HET PIN_nDISABLE input of the N2HET module.
When PINMMR9[0] = 0 and PINMMR9[1] = 1, EQEPERR is inverted and double-synchronized using VCLK before connecting directly to the N2HET PIN_nDISABLE input of the N2HET module.
PINMMR9[0] = 0 and PINMMR9[1] = 0 is an illegal combination and behavior defaults to PINMMR9[0] = 1.
