16.8 Baud Rate Generator
R01UH0017EJ0400 Rev.4.00
Sep 30, 2010
The BRG1, BRG2 and CSIB0 to CSIB2 baud rate generators are connected as shown in the following block diagram.
(1) Prescaler mode registers 1, 2 (PRSM1, PRSM2)
The PRSM1 and PRSM2 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, 2)
PRSMm
After reset: 00H
Cautions 1. Do not rewrite the PRSMm register during operation.
