I2C General Call Commands
The device acknowledges the general call address
command (0x00 in the first byte). The meaning of the
general call address is always specified in the second
byte. The I2C specification does not allow the use of
“00000000” (00h) in the second byte. Refer to the
Philips I2C document for more details of the General
Call specifications.
The MCP4728 device supports the following I2C
General Calls:
General Call Reset
General Call Wake-Up
General Call Software Update
General Call Read Address Bits
5.4.1
GENERAL CALL RESET
The
General Call Reset occurs if the second byte is
“00000110” (06h). At the acknowledgement of this
byte, the device will abort the current conversion and
perform the following tasks:
Internal Reset similar to a Power-on Reset (POR).
The contents of the EEPROM are loaded into
each DAC input and output registers immediately
VOUT will be available immediately regardless of
the LDAC pin condition
FIGURE 5-3:
General Call Reset.
5.4.2
GENERAL CALL WAKE-UP
If the second byte is “00001001” (09h), the device will
reset the Power-Down bits (PD1, PD0 = 0,0).
