Execution Sequence:
1, 2, 3... 1.
PC: The self-holding circuit (04001) is set on the leading edge of the
start statement pulse. The PC then sets an interrupt number and sets
the WRITE flag (10001).
2.
ASCII: Branches to an interrupt routine (statements 100 to 120) after the
interrupt is enabled by the ON PC statement and then reads the data
with the PC READ “@...” statement.
3.
PC: Changes the interrupt number to 0 to disable further interrupts after
all the data has been transferred to the ASCII Unit (i.e. when the ASCII
busy flag (10300) has been cleared).
