This figures shows the timing for H
p
= 8.
For H
= 7, time shown by “b” becomes zero. For H
p
= 6, time shown by “a” and “b”
become zero.
Therefore, the number of clock pulses during T1 become 4, 3, or 2 in the case of H
p
= 8,
H
p
= 7, or H
p
= 6 respectively.
The waveform for instructions with memory read is shown with a dash line. In other cases,
the waveform shown with a solid line is generated.
When an instruction with RAM read/write is executed, the value of cursor address is
output. In other cases, invalid data is output.
When an instruction with RAM read is executed, HD61830B latches the data at this timing.
In other cases, this data is invalid.
