Description

Master Configuration Register 1

Fields

PRESCALE

Prescaler

0 (000): Divide by 1.

1 (001): Divide by 2.

2 (010): Divide by 4.

3 (011): Divide by 8.

4 (100): Divide by 16.

5 (101): Divide by 32.

6 (110): Divide by 64.

7 (111): Divide by 128.
AUTOSTOP

Automatic STOP Generation

0 (0): No effect.

1 (1): STOP condition is automatically generated whenever the transmit FIFO is empty and LPI2C master is busy.
IGNACK

When set, the received NACK field is ignored and assumed to be ACK

0 (0): LPI2C Master will receive ACK and NACK normally.

1 (1): LPI2C Master will treat a received NACK as if it was an ACK.
TIMECFG

Timeout Configuration

0 (0): Pin Low Timeout Flag will set if SCL is low for longer than the configured timeout.

1 (1): Pin Low Timeout Flag will set if either SCL or SDA is low for longer than the configured timeout.
MATCFG

Match Configuration

0 (000): Match disabled.

2 (010): Match enabled (1st data word equals MATCH0 OR MATCH1).

3 (011): Match enabled (any data word equals MATCH0 OR MATCH1).

4 (100): Match enabled (1st data word equals MATCH0 AND 2nd data word equals MATCH1).

5 (101): Match enabled (any data word equals MATCH0 AND next data word equals MATCH1).

6 (110): Match enabled (1st data word AND MATCH1 equals MATCH0 AND MATCH1).

7 (111): Match enabled (any data word AND MATCH1 equals MATCH0 AND MATCH1).
PINCFG

Pin Configuration

0 (000): LPI2C configured for 2-pin open drain mode.

1 (001): LPI2C configured for 2-pin output only mode (ultra-fast mode).

2 (010): LPI2C configured for 2-pin push-pull mode.

3 (011): LPI2C configured for 4-pin push-pull mode.

4 (100): LPI2C configured for 2-pin open drain mode with separate LPI2C slave.

5 (101): LPI2C configured for 2-pin output only mode (ultra-fast mode) with separate LPI2C slave.

6 (110): LPI2C configured for 2-pin push-pull mode with separate LPI2C slave.

7 (111): LPI2C configured for 4-pin push-pull mode (inverted outputs).
