Node 616

This node functions as a wire node from 617 to 615. It is also a character clock gate and frequency divider.

Source code

Definitions

go

Wait for signal from RIGHT. If negative, characters are to be clocked out, thus send the signal to LEFT, and discard next three pusles. Otherwise just discard four clock pulses.

init

Set registers A and B, and jump to go.

Description

This note gates character clock signal. When characters are being rendered, it divides clock signal from node 617 by four, and sends it to node 615. Otherwise it blocks the clock signal. Output signal has 500 ns intervals.
