Write Data
Normal and High Voltage
The Write Command can be issued to both the Volatile
and Non-Volatile memory locations. The format of the
command, see Figure 7-2, includes the I2C Control
Byte, an A bit, the MCP4XXX Command Byte, an A bit,
the MCP4XXX Data Byte, an A bit, and a Stop (or
Restart) condition. The MCP4XXX generates the A / A
bits.
A Write command to a Volatile memory location
changes that location after a properly formatted Write
Command and the A / A clock have been received.
7.4.1
SINGLE WRITE TO VOLATILE
MEMORY
For volatile memory locations, data is written to the
MCP4XXX after every byte transfer (during the
Acknowledge). If a Stop or Restart condition is gener-
ated during a data transfer (before the A), the data will
not be written to the MCP4XXX. After the A bit, the
master can initiate the next sequence with a Stop or
Restart condition.
Refer to Figure 7-2 for the byte write sequence.
7.4.2
CONTINUOUS WRITES TO
VOLATILE MEMORY
A continuous write mode of operation is possible when
writing to the volatile memory registers (address 00h,
01h, and 04h). This continuous write mode allows
writes without a Stop or Restart condition or repeated
transmissions of the I2C Control Byte. Figure 7-3
shows the sequence for three continuous writes. The
writes do not need to be to the same volatile memory
address. The sequence ends with the master sending
a STOP or RESTART condition.
7.4.3
THE HIGH VOLTAGE COMMAND
(HVC) SIGNAL
The
High
Voltage
Command
(HVC)
signal
is
multiplexed with Address 0 (A0) and is used to indicate
that the command, or sequence of commands, are in
the High Voltage operational state. High Voltage
commands allow the device’s WiperLock Technology
and write protect features to be enabled and disabled.
The HVC pin has an internal resistor connection to the
MCP45XX/46XXs internal VDD signal.
