RELATIONSHIP BETWEEN PINS AND CONTROL REGISTERS
In this device, the same function is controlled by either a pin or a control register.
For example, when a function is controlled by a pin, setting of the corresponding control register is important.
Table 3 shows the relationship between settings of pins when functions are controlled by control registers and
setting of control registers when functions are controlled by pins. The setting value of a control register when a
function is controlled by a pin is equal to its initial value when the device is reset by the PDN/RST pin or the
PDN/RST bit (CR0-B7).
