The Digital Read command utilizes the combined I
the chip using the write data direction. Then the data direction is reversed by sending a repeated
start condition, and the slave address with R/W set to 1. After this, the slave device (ISD5100-
Series) begins to send data to the master until the master generates a NACK. If the part encounters
an overflow condition, the
possible due to the master generating ACK signals.
Digital Write and Digital Read can be done a “block” at a time. Thus, only 64 bits need be read in
each Digital Read command sequence.
An explanation and graphical representation of the Erase, Write and Read operations are found
below.
Note: All sequences assumes that the chip is in power-down mode before the commands are sent.
