Figure 8. Write Cycle Polling Flowchart using ACK
Minimizing System Delays by Polling On ACK
During the internal Write cycle, the device discon-
nects itself from the bus, and writes a copy of the
data from its internal latches to the memory cells.
The maximum Write time (t
w
) is shown in Table
12, but the typical time is shorter. To make use of
this, a polling sequence can be used by the bus
master.
The sequence, as shown in Figure 8, is:
– Initial condition: a Write cycle is in progress.
– Step 1: the bus master issues a Start condition
followed by a Device Select Code (the first byte
of the new instruction).
– Step 2: if the device is busy with the internal
Write cycle, no Ack will be returned and the bus
master goes back to Step 1. If the device has
terminated the internal Write cycle, it responds
with an Ack, indicating that the device is ready
to receive the second part of the instruction (the
first byte of this instruction having been sent
during Step 1).
