Input/Output (I/O) Ports
10.2 Port A
Port A is an 8-bit special function port that shares all of its pins with the keyboard interrupt (KBI) module
(see
8 Multi-Master IIC Interface
corresponding port pin is configured as input port. PTA0–PTA5 and PTA7 has direct LED drive capability.
10.2.1 Port A Data Register (PTA)
The port A data register (PTA) contains a data latch for each of the eight port A pins.
PTA[7:0] — Port A Data Bits
KBI7–KBI0 — Port A Keyboard Interrupts
SCL and SDA — MMIIC Module Pins
140
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.
The keyboard interrupt enable bits, KBIE[7:0], in the keyboard interrupt control register (KBIER) enable
the port A pins as external interrupt pins,
The MMIIC pins can be configured to use PTA2 and PTA3 as IIC communication pins, see
Multi-Master IIC Interface
CONFIG2 option bit, to allow PTA2/PTA3 to be MMIIC pins (see
(CONFIG2)).
