SERIAL COMMUNICATIONS INTERFACE (Cont’d)
EXTENDED RECEIVE PRESCALER DIVISION
REGISTER (SCIERPR)
Read/Write
Reset Value: 0000 0000 (00h)
Allows setting of the Extended Prescaler rate divi-
sion factor for the receive circuit.
Bits 7:0 = ERPR[7:0] 8-bit Extended Receive
Prescaler Register.
The extended Baud Rate Generator is activated
when a value different from 00h is stored in this
register. Therefore the clock frequency issued
from the 16 divider (see
the binary factor set in the SCIERPR register (in
the range 1 to 255).
The extended baud rate generator is not used af-
ter a reset.

EXTENDED TRANSMIT PRESCALER DIVISION
REGISTER (SCIETPR)
Read/Write
Reset Value:0000 0000 (00h)
Allows setting of the External Prescaler rate divi-

Bits 7:0 = ETPR[7:0] 8-bit Extended Transmit
Prescaler Register.
The extended Baud Rate Generator is activated
when a value different from 00h is stored in this
