3.7.20 Port V (PV6, PV7)
Ports V6 and V7 are 2-bit general-purpose I/O ports. Each bit can be set individually for
input or output. Resetting sets port V6 and V7 to input port and output latch to “0”.
In addition to functioning as general-purpose I/O port, PV can also function as a input or
output pin for SBI (SDA, SCL).
Setting in the corresponding bits of PVCR and PVFC enables the respective functions.
