Random Access Port - Reset Timing
Random Access Port Restart Timing of Sequential Port
(Internal Signal)
NOTES:
1. The sequential port is in the STOP mode and is being restarted from the random port by the Bit 4 Counter Release (see Case 5).
2. "0" is written to Bit 4 from the random port at address [A
3. CLR is an internal signal only and is shown for reference only.
4. Sequential port must also prohibit SR/W or SCE from being LOW for t
