Description
The I2C Data Buffer Register (I2C_BUF) is the CPU read/write interface to the data buffer. Whenever
this register is read, the data at the location pointed to by CPU current pointer (CPU_CP) is returned.
Similarly, whenever this register is written, the data is transferred to the buffer and written at the loca-
tion pointed to by the CPU current pointer (CPU_CP). Whenever this register is read without initializ-
ing the RAM contents either through the I2C or CPU interface, no valid value is returned.
