3.1.4.2.3 IOCELL Control Register
These registers set IOCELL of each I/O pin. Table I/O Configuration-14 shows overview of registers. Figure I/O
Configuration-8 shows a visualized function inside IOCELL controlled by the parameter that is set by IOCELL
control register. And Table I/O Configuration-15Table I/O Configuration-15 Correspondence Table of IOCELL
Control Registers and Controllable I/O Pinsshows correspondence table of registers and I/O pins.
