Figure 23-2. Flash Parallel Programming Device Connections
Note:
Sampling of pin P3.1 (RDY/BSY) is optional. During Parallel Programming, P3.1 will be pulled low
while the device is busy. Note that it does not require an external passive pull-up to VCC.
While CS is high, the interface is reset to its default state and P1 is tri-stated. CS should be
brought low before the first byte of a command is issued, and should return high only after the
last byte of the command has been strobed. Figure 23-3 shows a generic parallel write com-
mand sequence. Command, address, and data bytes are sampled from P1 on the rising edge of
the XTAL1 pulse. Figure 23-4 shows a generic parallel read command sequence. Command
and address bytes are sampled from P1 on the rising edge of the XTAL1 pulse. At the falling
edge of the fourth XTAL1 pulse the device enables P1 to output data. The data remains on P1
until CS is brought high. During reads the parallel programmer should tri-state P1 before the
negative edge of the fourth XTAL1 pulse to avoid bus contention.
