Monitor ROM (MON)
10.4.6 Baud Rate
Technical Data
166
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).
