FIGURE 4-7: DATA MEMORY MAP FOR PIC18FXX80/XX85 DEVICES Bank 0 Bank 1 Bank 12 Bank 15 Data Memory Map BSR<3:0> = 0000 = 0001 = 1110 = 1111 060h 05Fh F60h FFFh 00h 5Fh 60h FFh Access Bank When a = 0, the BSR is ignored and the Access Bank is used. The first 96 bytes are General Purpose RAM (from Bank 0). The second 160 bytes are Special Function Registers (from Bank 15). When a = 1, the BSR is used to specify the RAM location that the instruction uses.
