Description
Reserved bits.
Slave Transmit Interrupt Enable bit.
Set this bit to enable an interrupt after a slave transmits a byte.
Clear this interrupt source.
Slave Receive Interrupt Enable bit.
Set this bit to enable an interrupt after the slave receives data.
Clear this interrupt source.
I
Set this bit to enable an interrupt on detecting a Stop condition on the I
Clear this interrupt source.
I
Set this bit to no acknowledge (NACK).the next byte in the transmission sequence.
Clear this bit to let the Hardware control the acknowledge/no acknowledge sequence.
I
Set this bit to 1 to enable clock stretching. When SCL is low, setting this bit forces the device to hold SCL low until
I2CSSEN is cleared. If SCL is high, setting this bit forces the device to hold SCL low after the next falling edge.
Clear this bit to disable clock stretching.
I
Setting this bit enables a Transmit Request interrupt just after the positive edge of SCL during the Read bit
transmission.
Clear this bit to enable a Transmit Request interrupt just after the negative edge of SCL during the Read bit
transmission.
I
Writing a 1 to this bit clears the General Call Status and ID bits in the I2CSSTA register.
Clear this bit at all other times.
I
Set this bit and I2CGCEN to enable Hardware General call recognition in slave mode.
Clear to disable recognition of Hardware General Call commands.
I
Set this bit to allow the slave acknowledge I
Clear to disable recognition of general call commands.
Always set this bit = 0.
