bit 7
GCEN: General Call Enable bit (Slave mode only)
1 = Enable interrupt when a general call address (0000h) is received in the SSPSR
0 = General call address disabled
ACKSTAT: Acknowledge Status bit (Master Transmit mode only)
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
ACKDT/ADMSK5: Acknowledge Data bit
In Master Receive mode:
1 = Not Acknowledge
0 = Acknowledge
In Slave mode:
1 = Address masking of ADD5 enabled
0 = Address masking of ADD5 disabled
ACKEN/ADMSK4: Acknowledge Sequence Enable bit
In Master Receive mode:
1 = Initiate Acknowledge sequence on SDA and SCL pins and transmit ACKDT data bit.
0 = Acknowledge sequence Idle
In Slave mode:
1 = Address masking of ADD4 enabled
0 = Address masking of ADD4 disabled
RCEN/ADMSK3: Receive Enable bit
In Master Receive mode:
1 = Enables Receive mode for I
0 = Receive Idle
In Slave mode:
1 = Address masking of ADD3 enabled
0 = Address masking of ADD3 disabled
PEN/ADMSK2: Stop Condition Enable bit
In Master mode:
1 = Initiate Stop condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Stop condition Idle
In Slave mode:
1 = Address masking of ADD2 enabled
0 = Address masking of ADD2 disabled
RSEN/ADMSK1: Repeated Start Condition Enable bit
In Master mode:
1 = Initiate Repeated Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Repeated Start condition Idle
In Slave mode (7-Bit Addressing mode):
1 = Address masking of ADD1 enabled
0 = Address masking of ADD1 disabled
In Slave mode (10-Bit Addressing mode):
1 = Address masking of ADD1 and ADD0 enabled
0 = Address masking of ADD1 and ADD0 disabled
