20.2.7 Port Group Setting Register n (PGRn) (n = 1, 2)
The PGRn register specifies a group of I/O ports. Among the ports, ports corresponding to bits set to 1 in the register are
selected for a port group.
For example, when the PGR6 and PGR3 bits in the PGR1 register are set to 1, the PB6 and PB3 pins are selected to a port
group.
Table 20.4 shows the PGRn register and corresponding ports.
