5.3.2 Input/Output Mode/Control Mode Setting
control mode is specified by means of the PWM control register (PWMC) as shown in Table 5-4.
mode is specified by means of the port 1 mode control register (PMC1) as shown in Figure 5-15.
The port 1 input/output mode is set for each pin by means of the port 1 mode register (PM1) as shown in Figure 5-14.
In addition to their input/output port function, P10 and P11 also have a dual function as PWM signal output pins, and the
In addition to their input/output port function, P12 to P14 also have a dual function as serial interface pins, and the control
