16.3.1.6 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 Section 5. Clock Generator Module (CGM).)
