The I
formatted, so this section specifies the MCP47X6’s I
command formats and operation.
The commands can be grouped into the following
categories:
• Write memory
• Read memory
• General Call commands
The supported commands are shown in
Many of these commands allow for continuous
operation. This means that the I
generate a Stop bit but repeats the required data/
clocks. This allows faster updates since the overhead
of the I
supported commands and the required number of bit
clocks for both single and continuous commands.
Write commands, determined by the R/W bit = ‘0’, use
up to three command codes bits (C2:C0) to determine
the write’s operation.
The Read command is strictly determined by the R/W
bit = ‘1’. There are two formats of the command. One
for 12-bit and 10-bit devices and a second for 8-bit
devices.
The
specification reserved General Call command address
and command codes.
