Notes:
1. Timing Reference uses 0.9 V
2. Interrupt request through Port 3 (P33–P31).
3. Interrupt request through Port 3 (P30).
4. SMR – D5 = 0.
5. For internal RC oscillator.
DS (Output, Active Low)
AS (Output, Active Low)
Table 8. Additional Timing (Continued)
The Data Strobe is activated one time for each external memory transfer. For a
READ operation, data must be available prior to the trailing edge of DS. For
WRITE operations, the falling edge of DS indicates that output data is valid.
Address Strobe is pulsed one time at the beginning of each machine cycle.
Address output is through Port 0/Port 1 for all external programs. Memory address
transfers are valid at the trailing edge of AS. Under program control, AS is placed
in the high-impedance state along with Ports 0 and 1, Data Strobe, and Read/
Write.
