Port V0 to V2, V6 and V7 are 5-bit general-purpose I/O ports. Each bit can be set
individually for input or output. Resetting sets port V0 to V2, V6 and V7 to input port and
output latch to "0". In addition to functioning as general-purpose I/O port pins, PV can also
function as input or output pin for SBI (SDA, SCL) and output for SIO(SCLK0) (Note).
Above setting is used the control register PVCR and function register PVFC.
Port V3 and V4 are 2-bit general-purpose output ports. Resetting clear port V3 and V4 to
output latch to "0".
