Input/Output (I/O) Ports
16.2 Port A
Port A is an 8-bit special-function port that shares all of its pins with the analog-to-digital converter (ADC)
module. Port A pins also have LED direct drive capability.
16.2.1 Port A Data Register (PTA)
The port A data register contains a data latch for each of the eight port A pins.
PTA[7:0] — Port A Data Bits
ADC7–ADC0 — ADC Channels 7 to 0
LED drive — Direct LED drive pins
16.2.2 Data Direction Register (DDRA)
Data direction register A determines whether each port A pin is an input or an output. Writing a logic 1 to
a DDRA bit enables the output buffer for the corresponding port A pin; a logic 0 disables the output buffer.
260
These read/write bits are software-programmable. Data direction of each port A pin is under the control
of the corresponding bit in data direction register A. Reset has no effect on port A data.
ADC7–ADC0 are pins used for the input channels to the analog-to-digital converter module. The
channel select bits, ADCH[4:0], in the ADC status and control register define which port pin will be used
as an ADC input and overrides any control from the port I/O logic.
PTA7–PTA0 pins can be configured for direct LED drive. See
(LEDA).
Alternative Function:
Additional Function: LED drive
Address:
Care must be taken when reading port A while applying analog voltages to
ADC7–ADC0 pins. If the appropriate ADC channel is not enabled,
excessive current drain may occur if analog voltages are applied to the
PTAx/ADCx pin, while PTA is read as a digital input. Those ports not
selected as analog input channels are considered digital I/O ports.
