ADE7753
ADE7753 Serial Write Operation
The serial write sequence takes place as follows. With the
ADE7753 in communications mode (i.e., the CS input logic
low), a write to the communications register first takes place.
The MSB of this byte transfer is a 1, indicating that the data
transfer operation is a write. The LSBs of this byte contain the
address of the register to be written to. The ADE7753 starts
shifting in the register data on the next falling edge of SCLK. All
remaining bits of register data are shifted in on the falling edge
of subsequent SCLK pulses—see Figure 92 . As explained earlier,
the data write is initiated by a write to the communications
register followed by the data. During a data write operation to
the ADE7753, data is transferred to all on-chip registers one
byte at a time. After a byte is transferred into the serial port,
there is a finite time before it is transferred to one of the
ADE7753 on-chip registers. Although another byte transfer to
the serial port can start while the previous byte is being
should not finish until at least 4 μs after the end of the previous
byte transfer. This functionality is expressed in the timing
specification t 6 —see Figure 92. If a write operation is aborted
during a byte transfer (CS brought high), then that byte cannot
be written to the destination register.
Destination registers can be up to 3 bytes wide—see the
ADE7753 Register Description tables. Therefore the first byte
shifted into the serial port at DIN is transferred to the MSB
(most significant byte) of the destination register. If, for
example, the addressed register is 12 bits wide, a 2-byte data
transfer must take place. The data is always assumed to be right
justified, therefore in this case, the four MSBs of the first byte
would be ignored and the four LSBs of the first byte written to
the ADE7753 would be the four MSBs of the 12-bit word.
