Note
1. When the ports are set to memory interface signals, their states are controlled by MEM0CONSTOP in stop
mode, MEM0CONSLP0 in sleep mode
2. When the ports GPQ[4:0] and GPQ[8:7] are set to memory interface signals, the pull-up/down are disabled
3. When the ports GPQ[6:5] are set to memory interface signals, the pull-up/down, the pull-up/down are
controlled by SPCON[11:10]
