19.3.1.1 Normal Monitor Mode
When V
divide-by-two of the input clock. If PTC3 is high with V
bus frequency will be a divide-by-four of the input clock. Holding the PTC3 pin low when entering monitor
mode causes a bypass of a divide-by-two stage at the oscillator only if V
event, the CGMOUT frequency is equal to the CGMXCLK frequency, and the OSC1 input directly
generates internal bus clocks. In this case, the OSC1 signal must have a 50% duty cycle at maximum bus
frequency.

Function
[Pin No.]
1. PTA0 must have a pullup resistor to VDD in monitor mode.
2. Communication speed in the table is an example to obtain a baud rate of 9600.
3. External clock is a 4.1952 MHz or 9.8304 MHz canned oscillator on OSC1.
4. X = don’t care.
5. MON08 pin refers to P&E Microcomputer Systems’ MONOUT-Cyclone 2 by 8-pin connector.
Mode
Baud rate using external oscillator is bus frequency / 256.
