Network Output Data
Table R2.1 Network Output Data Format
Command Word Format
Bit 15, Transmit Bit -
Used to control the flow of programming data to the NXEE2. The NXEE2 will not
accept new programming data until this bit makes a 0
1 transition. Once this bit is set, it should
remain set until the NXEE2 responds by setting the Acknowledge bit in the Network Input data. See
on page 13 for a complete explanation of the NXEE2 programming sequence.
Bit 14, Save to FLASH Memory -
This bit is used to store parameter values and calculated offsets into non-
volatile FLASH memory. Once stored, the parameter values will be used on every power up. This
means that you will not have to configure the NXEE2 on every start up.
The FLASH memory is limited to 10,000 write cycles. Do not save the offset to non-
volatile memory more than necessary to prevent a failure in the NXEE2.
Bits 13-6, Reserved -
Must be set to ‘0’. A command error will result if any of these bits are set to ‘1’ when
the Transmit Bit makes a 0
1 transition.
This reference chapter details the output and input data formats used to commu-
nicate with the NXEE2.
