R5 and R5DD register: R5 is an 2-bit CMOS bidirection-

al I/O port (address 0CAH). Each I/O pin can independent-

ly used as an input or an output through the R5DD register

(address 0CBH).

R6 and R6DD register: R6 is an 4-bit CMOS bidirection-

al I/O port (address 0CCH). Each I/O pin can independent-

ly used as an input or an output through the R6DD register

(address 0CDH).

R6DD (address CDH) controls the direction of the R6 pins,

even when they are being used as analog inputs. The user

must make sure to keep the pins configured as inputs when

using them as analog inputs.

Alternate Function

AN4 (ADC input 4)

AN5 (ADC input 5)

AN6 (ADC input 6)

AN7 (ADC input 7)

The control register PMR5 (address D1H) controls the se-

lection alternate function. After reset, this value is “0”, port

may be used as general I/O ports. To use buzzer function,

write “1” to the PMR5 and the pin R55 must be defined as

output mode (the bit 5 of R5DD=1)

R55

Alternate Function

WDTO (Watchdog timer output)

BUZ (Square-wave output for buzzer)
