SMP: Slew Rate Control bit
In Master or Slave mode:
1 = Slew rate control disabled for Standard Speed mode (100 kHz and 1 MHz)
0 = Slew rate control enabled for High Speed mode (400 kHz)
CKE: SMBus Select bit
In Master or Slave mode:
1 = Enable SMBus specific inputs
0 = Disable SMBus specific inputs
D/A: Data/Address bit
In Master mode:
Reserved
In Slave mode:
1 = Indicates that the last byte received or transmitted was data
0 = Indicates that the last byte received or transmitted was address
P: STOP bit
1 = Indicates that a STOP bit has been detected last
0 = STOP bit was not detected last
Note:
S: START bit
1 = Indicates that a start bit has been detected last
0 = START bit was not detected last
Note:
R/W: Read/Write bit Information (I
In Slave mode:
1 = Read
0 = Write
In Master mode:
1 = Transmit is in progress
0 = Transmit is not in progress
Note:
UA: Update Address (10-bit Slave mode only)
1 = Indicates that the user needs to update the address in the SSPADD register
0 = Address does not need to be updated
BF: Buffer Full Status bit
In Transmit mode:
1 = Receive complete, SSPBUF is full
0 = Receive not complete, SSPBUF is empty
In Receive mode:
1 = Data transmit in progress (does not include the ACK and STOP bits), SSPBUF is full
0 = Data transmit complete (does not include the ACK and STOP bits), SSPBUF is empty
Legend:
R = Readable bit
- n = Value at POR
SSPSTAT: MSSP STATUS REGISTER (I
R/W-0
Note:
SMP
This bit is cleared on RESET and when SSPEN is cleared.
This bit is cleared on RESET and when SSPEN is cleared.
This bit holds the R/W bit information following the last address match. This bit is only
valid from the address match to the next START bit, STOP bit, or not ACK bit.
ORing this bit with SEN, RSEN, PEN, RCEN, or ACKEN will indicate if the MSSP is
in IDLE mode.
