Progread
Note: If the expected read command is not from the next higher register to the previous read or write command, then set a
known “read” register address prior to a read operation by issuing the following command:
Prior to Progread Command Set Register Address
The user can ignore the STOP condition above and use a repeated START condition instead, straight after the slave
acknowledgement bit (i.e., followed by the Progread command):
Progread Command Frame
Progsave
Note:
PROGWRITE is for writing to the IDT5V49EE704 registers.
PROGREAD is for reading the IDT5V49EE704 registers.
PROGSAVE is for saving all the contents of the IDT5V49EE704 registers to the EEPROM.
PROGRESTORE is for loading the entire EEPROM contents to the IDT5V49EE704 registers.
Progrestore
EEPROM Interface
The IDT5V49EE704 can also store its configuration in an internal EEPROM. The contents of the device's internal
programming registers can be saved to the EEPROM by issuing a save instruction (ProgSave) and can be loaded back to
the internal programming registers by issuing a restore instruction (ProgRestore).
To initiate a save or restore using I2C, only two bytes are transferred. The Device Address is issued with the read/write bit
set to “0”, followed by the appropriate command code. The save or restore instruction executes after the STOP condition is
issued by the Master, during which time the IDT5V49EE704 will not generate Acknowledge bits. The IDT5V49EE704 will
acknowledge the instructions after it has completed execution of them. During that time, the I2C bus should be interpreted
as busy by all other users of the bus.
On power-up of the IDT5V49EE704, an automatic restore is performed to load the EEPROM contents into the internal
programming registers. The IDT5V49EE704 will be ready to accept a programming instruction once it acknowledges its 7-bit
I2C address.
