The MCP2140A serial interface and IR baud rates are
fixed at 9600 baud, given a 3.6864 MHz device clock.
2.1
Any time the device is powered up
the Power-Up Timer delay
lowed by an Oscillator Start-up Timer (OST) delay
(Parameter
nication with the device may be initiated. This commu-
nication is from both the infrared transceiver’s side and
the controller’s UART interface.
2.1.1
When any state machine is operated outside of its’
specified operating conditions, undesired operation
may occur. Application validation should be done to
determine when the system exits from either a
power-on or a brown-out conditions if the MCP2140A
requires the use of an external voltage supervisory cir-
cuit to ensure proper system operation.

The MCP2140A is forced into the reset state when the
RESET pin is in the low state. Once the RESET pin is
brought to a high state, the Device Reset sequence
occurs. Once the sequence completes, functional
operation begins.
2.3
The MCP2140A requires a clock source to operate.
This clock source is used to eystablish the device tim-
ing, including the device “Bit Clock”.
2.3.1
The clock source can be supplied by one of the
following:
• Crystal
• Resonator
• External clock
The frequency of this clock source must be
