30.2.1.3 Flow Control

Flow control is accomplished using the three jump commands, PTGJMP, PTGJMPC0 and PTGJMPC1. These jump commands are three bits to allow a larger 5-bit OPTION to match that of the Queue Pointer, PTGQPTR. The PTGJMP command simply jumps to the specified queue location, whereas the PTGJMPCx commands are conditional jumps based on the comparison of the counters to the PTG Counter Limit registers (PTGCxLIM).
