19.8 Baud Rate Generator
diagram.
The BRG1 to BRG4 baud rate generators are connected to CSIF0 to CSIF6 as shown in the following block
(1) Prescaler mode registers 1 to 4 (PRSM1 to PRSM4)
The PRSMm registers control generation of the baud rate signal for CSIF.
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
(m = 1 to 4)
PRSMm
After reset: 00H
Cautions 1. Do not rewrite the PRSMm register during operation.
