VPCTRLB - Virtual Port-map Control Register B
• Bit 7:4 - VP1MAP: Virtual Port 1 Mapping
These bits decide which ports should be mapped to Virtual Port 1. The registers DIR, OUT, IN
and INTFLAGS will be mapped. Accessing the virtual port registers is equal to accessing the
actual port registers. See
• Bit 3:0 - VP0MAP: Virtual Port 0 Mapping
These bits decide which ports should be mapped to Virtual Port 0. The registers DIR, OUT, IN
and INTFLAGS will be mapped. Accessing the virtual port registers is equal to accessing the
actual port registers. See
• Bit 7:4 - VP3MAP: Virtual Port 3 Mapping
These bits decide which ports should be mapped to Virtual Port 3. The registers DIR, OUT, IN
and INTFLAGS will be mapped. Accessing the virtual port registers is equal to accessing the
actual port registers. See
• Bit 3:0 - VP2MAP: Virtual Port 2 Mapping
These bits decide which ports should be mapped to Virtual Port 2. The registers DIR, OUT, IN
and INTFLAGS will be mapped. Accessing the virtual port registers is equal to accessing the
actual port registers. See
Table 13-6.
