ID Register (12h)
The ID register provides the value for both the part number and silicon revision number for that part number.
It is a read-only register whose value never changes.

va Constant (13h)
ill The CONSTANT register provides a means to facilitate SMBus block transfers that is used as the Byte Count
in the SMBus protocol. For example, all four ADC Channel Data Registers can be read in a single SMBus block
t transfer if an SMBus Block Read is initiate at address 13h. This register defaults to the constant 4, but may be
set to other values depending upon the end application. For example, if manual integration is employed and
G s the register is set to 5, then all four ADC Channel Data Registers and the Manual Integration Timer Register
can be read in a single SMBus read block transaction.

DESCRIPTION
Constant value used as the byte count for SMBus block read/write transactions. I2C protocol does not use
the byte count field in the block transaction, so this register should be ignored if an TSL2581 device is used.
