EXTENDED RECEIVE PRESCALER DIVISION
REGISTER (ERPR)
Read/Write
Reset Value: 0000 0000 (00h)
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
register. Therefore the clock frequency issued
from the 16 divider (see Figure 54) 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
REGISTER (ETPR)
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
register. Therefore the clock frequency issued
from the 16 divider (see Figure 54) 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.
