Timing Waveform of Read with Port-to-port Delay No. 4 (for slave CY7C143)
[24, 25, 26]
Write Cycle No. 1 (OE Three-States Data I/Os - Either Port)
[17, 27]
Notes:
24. Assume BUSY input at V
for the writing port and at V
for the reading port.l
25. Write cycle parameters should be adhered to in order to ensure proper writing.
26. Device is continuously enabled for both ports.
27. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of t
PWE
or t
HZWE
+ t
SD
to allow the data I/O pins to enter high
impedance and for data to be placed on the bus for the required t
SD
.
