Description

Pin configuration register for I2C0-bus pins

Fields

SCL_EFP

Select input glitch filter time constant for the SCL pin.

0 (50_NS_GLITCH_FILTER): 50 ns glitch filter

1 (3_NS_GLITCH_FILTER): 3 ns glitch filter

RESERVED

Reserved. Always write a 0 to this bit.

SCL_EHD

Select I2C mode for the SCL pin.

0 (STANDARDFAST_MODE): Standard/Fast mode transmit

1 (FAST_MODE_PLUS_TRANS): Fast-mode Plus transmit

SCL_EZI

Enable the input receiver for the SCL pin. Always write a 1 to this bit when using the I2C0.

0 (DISABLED): Disabled

1 (ENABLED): Enabled

RESERVED

Reserved

SCL_ZIF

Enable or disable input glitch filter for the SCL pin. The filter time constant is determined by bit EFP.

0 (ENABLE_INPUT_FILTER): Enable input filter

1 (DISABLE_INPUT_FILTER): Disable input filter

SDA_EFP

Select input glitch filter time constant for the SDA pin.

0 (50_NS_GLITCH_FILTER): 50 ns glitch filter

1 (3_NS_GLITCH_FILTER): 3 ns glitch filter

RESERVED

Reserved. Always write a 0 to this bit.

SDA_EHD

Select I2C mode for the SDA pin.

0 (STANDARDFAST_MODE): Standard/Fast mode transmit

1 (FAST_MODE_PLUS_TRANS): Fast-mode Plus transmit

SDA_EZI

Enable the input receiver for the SDA pin. Always write a 1 to this bit when using the I2C0.

0 (DISABLED): Disabled

1 (ENABLED): Enabled

RESERVED

Reserved

SDA_ZIF

Enable or disable input glitch filter for the SDA pin. The filter time constant is determined by bit SDA_EFP.

0 (ENABLE_INPUT_FILTER): Enable input filter

1 (DISABLE_INPUT_FILTER): Disable input filter

RESERVED

Reserved
