10.4.6 Baud Rate
MC68HC908LD64
Freescale Semiconductor
—
Rev. 3.0
The communication baud rate is controlled by crystal frequency and the
state of the PTC3 pin upon entry into monitor mode. When PTC3 is high,
the divide by ratio is 1024. If the PTC3 pin is at logic zero upon entry into
monitor mode, the divide by ratio is 512.
