14.4.3 Dedicated baud rate generator
generates a serial clock for transmission/reception of UART0.
(1) Configuration of baud rate generator
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
The dedicated baud rate generator consists of a source clock selector and a 5-bit programmable counter, and
Separate 5-bit counters are provided for transmission and reception.
• Base clock
• Transmission counter
• Reception counter
The clock selected by bits 7 and 6 (TPS01 and TPS00) of baud rate generator control register 0 (BRGC0) is
supplied to each module when bit 7 (POWER0) of asynchronous serial interface operation mode register 0
(ASIM0) is 1. This clock is called the base clock and its frequency is called f
low level when POWER0 = 0.
This counter stops operation, cleared to 0, when bit 7 (POWER0) or bit 6 (TXE0) of asynchronous serial interface
operation mode register 0 (ASIM0) is 0.
It starts counting when POWER0 = 1 and TXE0 = 1.
The counter is cleared to 0 when the first data transmitted is written to transmit shift register 0 (TXS0).
This counter stops operation, cleared to 0, when bit 7 (POWER0) or bit 5 (RXE0) of asynchronous serial interface
operation mode register 0 (ASIM0) is 0.
It starts counting when the start bit has been detected.
The counter stops operation after one frame has been received, until the next start bit is detected.
