To set the value of either the Nonvolatile TLOW or THIGH Limit Register, the Master must first
initiate a START condition followed by the AT30TS750’s device address byte (1001AAA0 where
“AAA” corresponds to the hard-wired A2-0 address pins). After the AT30TS750 has received the
proper address byte, the device will send an ACK to the Master. The Master must then send the
appropriate Pointer Register byte of 12h to select the Nonvolatile TLOW Limit Register or 13h to
select the Nonvolatile THIGH Limit Register. After the Pointer Register byte has been sent, the
AT30TS750 will send another ACK to the Master. After receiving the ACK from the AT30TS750,
the Master must then send two data bytes to the AT30TS750 to set the value of the Nonvolatile
TLOW or THIGH Limit Register. Any subsequent bytes sent to the AT30TS750 will simply be
ignored by the device. If the Master does not send two complete bytes of data prior to issuing a
STOP or repeated START condition, then the AT30TS750 will ignore the data and the contents of
the register will not be changed.
After the Master has issued a STOP condition, the AT30TS750 will begin the internally self-timed
program operation, and the contents of the Nonvolatile TLOW or THIGH Limit Register will be
updated within a time of tPROG. During this time, the NVRBSY bit of the Configuration Register
will indicate that the device is busy. If the Master issues a repeated START condition instead of a
STOP condition, the AT30TS750 will abort the operation and the contents of the Nonvolatile
TLOW or THIGH Limit Register will not be changed.
In addition to the Master not sending two complete bytes of data, writing to the Nonvolatile TLOW
or THIGH Limit Register will be ignored and no operation will be performed under the following
conditions:
the nonvolatile registers are already busy (the NVRBSY bit of the Configuration
Register is in the logic “1” state), the volatile and nonvolatile registers are currently locked (the
RLCK bit of the Nonvolatile Configuration Register is in the logic “1” state), or the volatile and
nonvolatile registers are permanently locked down (the RLCKDWN bit of the Nonvolatile
Configuration Register is in the logic “1” state). However, the device will still respond with an
ACK, except in the case of the nonvolatile registers being busy, to indicate that it received the
proper data bytes even though the program operation will not be performed. In the case of the
nonvolatile registers being busy, the device will respond with an ACK to the address and pointer
bytes but will then NACK when the data bytes are sent from the Master.
In order to read the Nonvolatile TLOW or THIGH Limit Register, the Pointer Register must be set or
have been previously set to 12h to select the Nonvolatile TLOW Limit Register or 13h to select the
Nonvolatile THIGH Limit Register (if the previous operation was a write to one of the registers,
then the Pointer Register will already be set for that particular limit register).
If the Pointer
Register has already been set appropriately, the Nonvolatile TLOW or THIGH Limit Register can be
read by having the Master first initiate a START condition followed by the AT30TS750’s device
