¨ Sequential Write

The initial step of Sequential Write is the same as Random Write, after the receipt of each word data,

MTL003 will respond with an Acknowledge and then internal address counter will increment by one for next

data write. If the master stops writing data, it will generate stop condition. Ref. Fig. 3.5.3.

¨ Current Address Read

MTL003 contains an address counter which maintains the last access address incremented by one. If the last

access address is n, the read data should access from address n+1. Upon receipt of the slave address with

R/W bit set to 1, MTL003 generates an Acknowledge and transmits the eight bits data. After receiving data

the master will generate a stop condition instead of an Acknowledge. Ref. Fig. 3.5.4.
