the I
Bits 0–1—Reserved
These bits are reserved and must be set to 0.
REVD—Reverse Data
This bit determines the receive and transmit character bit order.
GCD—General Call Disable
This bit determines if the receiver will acknowledge a general call address.
FLT—Clock Filter
This bit determines if the I
PDIV—Pre Divider
This field determines the division factor of the clock before it is fed into the baud rate
generator. The clock source for the I
system interface unit.

0 = Normal operation. Most-significant bit of character transmitted and received first.
1 = Reverse data. Least-significant bit of character transmitted and received first.
0 = General call address is enabled.
1 = General call address is disabled.
0 = I2CLK is not filtered.
1 = I2CLK is filtered by a digital filter.
00 = Use the BRGCLK/32 as the input to the I
01 = Use the BRGCLK/16 as the input to the I
10 = Use the BRGCLK/8 as the input to the I
11 = Use the BRGCLK/4 as the input to the I
