4.2.12 Port 11
Port 11 is an I/O port with an output latch. Port 11 can be set to the input mode or output mode in 1-bit units using port
mode register 11 (PM11). When the P110 to P117 pins are used as an input port, use of an on-chip pull-up resistor can
be specified in 1-bit units by pull-up resistor option register 11 (PU11).
Input to the P115 to P117 pins can be specified as analog input or digital input in 1-bit units, using port mode control
register 11 (PMC11).
This port can also be used for A/D converter analog input.
Reset signal generation sets P110 to P114 to input mode, and sets P115 to P117 to analog input.
