CHAPTER 14 SERIAL INTERFACE UART6
Preliminary User’s Manual U16315EJ1V0UD
305
(b) Baud rate generator control register 6 (BRGC6)
This register selects the base clock of serial interface UART6.
BRGC6 can be set by an 8-bit memory manipulation instruction.
RESET input sets this register to FFH.
Remark
BRGC6 can be refreshed (the same value is written) by software during a communication
operation (when bit 7 (POWER6) and bit 6 (TXE6) of ASIM6 = 1 or bit 7 (POWER6) and bit 5
(RXE6) of ASIM6 = 1).
Address: FF57H After reset: FFH R/W

Cautions 1. Make sure that bit 6 (TXE6) and bit 5 (RXE6) of the ASIM6 register = 0 when rewriting the
MDL67 to MDL60 bits.
2. The baud rate value is the output clock of the 8-bit counter divided by 2.
Remarks 1.
f
XCLK
: Frequency of base clock (Clock) selected by the TPS63 to TPS60 bits of CKSR6 register
2.
k: Value set by MDL67 to MDL60 bits (k = 8, 9, 10, ..., 255)
