3.2 Read Operations with Address Increment
Read Data Byte (Read 8 Bits) (Fig.7)
In this operation the output of the protect bit is suppressed. The address is incremented after the
eighth clock pulse.
Read Data Byte together with Protect Bit (Read 9 Bits) (Fig. 8)
After command entry the eight data bits are read out by eight consecutive clock pulses, and the
protect bit on the ninth pulse. After the ninth clock pulse the address counter is incremented.
The read operation is terminated by a RST transition “0” to “1”.
