16.8 Baud Rate Generator
diagram.
548
The BRG1 to BRG3 and CSIB0 to CSIB4 baud rate generators are connected as shown in the following block
(1) Prescaler mode registers 1 to 3 (PRSM1 to PRSM3)
The PRSM1 to PRSM3 registers control generation of the baud rate signal for CSIB.
These registers can be read or written in 8-bit or 1-bit units.
Reset sets these registers to 00H.
(m = 1 to 3)
PRSMm
After reset: 00H
Cautions 1. Do not rewrite the PRSMm register during operation.
