7~1
I2ADDR.[7:1]
I2C Address register:
The 8051 uC can read from and write to this 8-bit, directly addressable
SFR. The content of this register is irrelevant when I2C is in master mode.
In the slave mode, the seven most significant bits must be loaded with the
MCU’s own address. The I2C hardware will react if either of the address is
matched.

FUNCTION
7-0
TA.[7:0]
The Timed Access register:
The Timed Access register controls the access to protected bits. To access
protected bits, the user must first write AAH to the TA. This must be immediately
followed by a write of 55H to TA. Now a window is opened in the protected bits
for three machine cycles, during which the user can write to these bits.
