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 I
(00h) in the second byte. Please refer to the Phillips I
document for more details on the General Call
specifications.
The MCP47X6 devices support the following I
general calls:
• General Call Reset
• General Call Wake-Up

At the falling edge of the SCL at the end of this ACK pulse a reset occurs (startup timer starts and DAC register latched).
The 2nd byte can be repeated after the 2nd by continued clocking before issuing Stop bit.

The device performs General Call Reset 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).
• This is a similar event to the POR. The V
This command allows multiple MCP47X6 devices to be
reset synchronously.
