Name and Functions
Port A:
The state of any pin in Port A is software programmable and every line is configured as
an input during any reset.
Port B:
The state of any pin in Port B is software programmable and every line is configured as an
input during any reset. Each I/O line contains a programmable interrupt/pull-up for keyscan.
Port C:
Every pin in Port C is a high-current pin and its state is software programmable. All lines
are configured as inputs during any reset.
IRO:
Suitable for driving IR LED biasing logic, the IRO pin is the high-current source and sink out-
put of the carrier modulator transmitter subsystem. Default state is low after any reset.
Low-Power Reset:
An active-low pin, LPRST# function sets MCU to low-power reset mode. Once the
device is in low-power reset mode, it is held in reset with all processor clocks and crystal oscillator halted.
An internal Schmitt trigger is included in the LPRST# pin to improve noise immunity.
Reset:
By setting the RST# pin low, the device is reset to a default state. An internal Schmitt trig-
ger is included in the RST# pin to improve noise immunity.
Oscillator 1,2:
These 2 pins interface with external oscillator circuits. A crystal
resonator, a ceramic resonator, or an external clock signal can be used.
Interrupt Request:
The IRQ# is negative edge-sensitive triggered. An internal Schmitt trigger is
included in the IRQ# pin to improve noise immunity.
Power Supply:
Supply Voltage (2.2-3.2V)
Ground:
Circuit ground. (0V reference)
