Bit Clock

The device crystal is used to derive the communication

bit clock (BITCLK). There are 16 BITCLKs for each bit

time. The BITCLKs are used for the generation of the

start bit and the eight data bits. The stop bit uses the

BITCLK when the data is transmitted (not for

reception).

This clock is a fixed frequency and has minimal

variation

in

frequency

(specified

by

crystal

manufacturer).

2.5

UART Interface

The UART interface communicates with the "control-

ler". This interface is a half duplex interface, meaning

that the system is either transmitting or receiving, but

not both simultaneously.

2.5.1

BAUD RATE

The baud rate for the MCP2150 serial port (the TX and

RX pins) is configured by the state of the BAUD1 and

BAUD0 pins. These two device pins are used to select

the baud rate at which the MCP2150 will transmit and

receive serial data (not IR data). Table 2-3 shows the

baud rate configurations.

2.5.2

TRANSMITTING

When the controller sends serial data to the MCP2150,

the controller’s baud rate is required to match the baud

rate of the MCP2150’s serial port.

2.5.3

RECEIVING

When the controller receives serial data from the

MCP2150, the controller’s baud rate is required to

match the baud rate of the MCP2150’s serial port.
