SERIAL COMMUNICATIONS INTERFACE (Cont’d)

EXTENDED RECEIVE PRESCALER DIVISION

Read/Write

Reset Value: 0000 0000 (00 h)

Allows setting of the Extended Prescaler rate divi-

sion factor for the receive circuit.

Bit 7:1 = ERPR[7:0]

8-bit Extended Receive Pres-

caler Register.

The extended Baud Rate Generator is activated

when a value different from 00h is stored in this

from the 16 divider (see Figure 3.) is divided by the

binary factor set in the ERPR register (in the range

1 to 255).

The extended baud rate generator is not used af-

ter a reset.

EXTENDED TRANSMIT PRESCALER DIVISION

Read/Write

Reset Value:0000 0000 (00h)

Allows setting of the External Prescaler rate divi-

sion factor for the transmit circuit.

Bit 7:1 = ETPR[7:0]

8-bit Extended Transmit Pres-

caler Register.

The extended Baud Rate Generator is activated

when a value different from 00h is stored in this

from the 16 divider (see Figure 3.) is divided by the

binary factor set in the ETPR register (in the range

1 to 255).

The extended baud rate generator is not used af-

ter a reset.
