DIR - Data Direction
OUT - Data Output Value
IN - Data Input Value
Table 13-8.
• Bit 7:0 - DIR[7:0]: Data Direction Register
This register sets the data direction for the individual pins in the port mapped by "VPCTRLA -
Virtual Port-map Control Register A" or "VPCTRLB - Virtual Port-map Control Register B". When
a port is mapped as virtual, accessing this register is identical to accessing the actual DIR regis-
ter for the port.
• Bit 7:0 - OUT[7:0]: Data Output value
This register sets the data output value for the individual pins in the port mapped by "VPCTRLA
- Virtual Port-map Control Register A" or "VPCTRLB - Virtual Port-map Control Register B".
When a port is mapped as virtual, accessing this register is identical to accessing the actual
OUT register for the port.
