R6 and R6IO register: R6 is an 8-bit CMOS bidirectional I/O
port (address 0CC_H). Each I/O pin can independently used as an
input or an output through the R6IO register (address 0CD_H).
In addition, Port R6 is multiplexed with AD converter analog in-
put AN0~AN7.

AN3 (ADC input channel 3)
AN4 (ADC input channel 4)
AN5 (ADC input channel 5)
AN6 (ADC input channel 6)
AN7 (ADC input channel 7)
R6IO (address CD_H) controls the direction of the R6 pins, except
when they are being used as analog input channels. The user don’t
have to keep the pins configured as inputs when using them as an-
alog input channels, because the analog input mode is activated
by the setting of ADC enable bit of ADCM register and ADC
channel selection.

R7 and R7IO register: R7 is an 8-bit CMOS bidirectional I/O
port (address 0CE_H). Each I/O pin can independently used as an
input or an output through the R7IO register (address 0CF_H). The
on-chip pull-up resistor can be connected to them in 1-bit units
with a R7 pull-up selection register (PU7).
In addition, Port R7 is multiplexed with AD converter analog in-
put channel AN8~AN15.
