BRH = I²C Baud Rate High Byte
Most significant byte, BRG[15:8], of the I²C Baud Rate Generator’s reload value.
Note: If the DIAG bit in the I²C Mode Register is set to 1, a read of the I2CBRH register returns
the current value of the I²C Baud Rate Counter[15:8].

BRL = I²C Baud Rate Low Byte
Least significant byte, BRG[7:0], of the I²C Baud Rate Generator’s reload value.
Note: If the DIAG bit in the I²C Mode Register is set to 1, a read of the I2CBRL register returns
the current value of the I²C Baud Rate Counter[7:0]
I²C State Register
The read-only I²C State Register provides information about the state of the I²C bus and
the I²C bus controller.
When the DIAG bit of the I²C Mode Register is cleared, this register provides information
on the internal state of the I²C controller and I²C bus, as shown in Table 97. A more
detailed discussion of each bit follows this table.
When the DIAG bit of the I²C Mode Register is set, this register returns the value of the
I²C controller state machine, as shown in Table 98, which follows on page 190.
