Bit 7–Bit 0
System Data Bus (bidirectional, tristate). This bus is used to transfer all
date and command words between the Z80 CPU and the Z80 CTC. There
are eight bits on this bus, of which bit 0 is the least-significant. CSI CSO
Channel Select (input, active High). These pins form a 2-bit binary address
code for selecting one of the four independent CTC channels for an I/O
Write or Read. (See Table 4).
