16.8 Baud Rate Generator
R01UH0015EJ0300 Rev.3.00
Sep 30, 2010
The BRG1 to BRG3 and CSIB0 to CSIB4 baud rate generators are connected as shown in the following block diagram.
(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.
