Doc ID 12370 Rev 8
Bits 2:0 = SCR[2:0] SCI Receiver rate divider.
These 3 bits, in conjunction with the SCP[1:0] bits define the total division applied to the bus
clock to yield the receive rate clock in conventional Baud Rate Generator mode.

Extended receive prescaler division register (SCIERPR)
Read/ write
Reset value: 0000 0000 (00h)
Bits 7:0 = ERPR[7:0] 8-bit Extended Receive Prescaler Register.
The extended baud rate generator is activated when a value other than 00h is stored in this
register. The clock frequency from the 16 divider (see Figure 79) is divided by the binary
factor set in the SCIERPR register (in the range 1 to 255).
The extended baud rate generator is not active after a reset.
