14.3.6 MC68HC908AS60A Baud Rate
With a 4.9152-MHz crystal and the PTC3 pin at logic 1 during reset, data is transferred between the
monitor and host at 4800 baud. If the PTC3 pin is at logic 0 during reset, the monitor baud rate is 9600.
When the CGM output, CGMOUT, is driven by the PLL, the baud rate is determined by the MUL[7:4] bits
in the PLL programming register (PPG). (See
