To operate using various clock frequencies over a range of baud rates, the serial interface
has an auto-baud detector. The auto-baud detector is used to automatically set up the baud
rate generator.
The auto-baud detector is set up to measure one of two different auto-baud characters,
(default) or
Encore!
UART, you can switch to an auto-baud character of
carriage return character and is sent using a terminal interface.
When using the auto-baud character
the falling edge at the beginning of the start bit to the rising edge at the beginning of data
bit 7. For the auto-baud character
the rising edge at the end of the start bit to the rising edge at the beginning of the stop bit.
This measured value is automatically written to the BRG reload register after the auto-
baud character is received. After it is configured, the BRG will generate a bit clock based
on this measured character time.
When operating at high speeds, it is appropriate to speed up the rise and fall times of the
single wire bus. Three control bits are used to control the bus rise and fall times, the high
drive strength enable bit, the drive high enable bit and the output enable control bit.
The high drive strength enable bit puts the pin into high drive mode. For information about
high drive strength, see the
If the output enable control bit is set, the line is driven High and Low during transmission.
If the drive high control bit is set, it drives the line high for short periods when transmit-
ting a logic one. This rapidly charges the inherent capacitance of the single wire bus.
If both the output enable and drive high control bits are set, the line is driven high for one
clock cycle when transmitting a one. If the output enable bit is clear and the drive high bit
