SSPSTAT: SYNCHRONOUS SERIAL PORT STATUS REGISTER (ADDRESS 94h)
bit 7
SMP: SPI Data Input Sample Phase bit
SPI Master mode:
1 = Input data sampled at end of data output time
0 = Input data sampled at middle of data output time (Microwire)
SPI Slave mode:
This bit must be cleared when SPI is used in Slave mode.
I
This bit must be maintained clear.
CKE: SPI Clock Edge Select bit
1 = Transmit occurs on transition from active to Idle clock state
0 = Transmit occurs on transition from Idle to active clock state
D/A: Data/Address bit (I
In I
1 = Indicates that the last byte received was data
0 = Indicates that the last byte received was address
P: Stop bit
1 = Indicates that a Stop bit has been detected last
0 = Stop bit was not detected last
S: Start bit
1 = Indicates that a Start bit has been detected last (this bit is ‘0’ on Reset)
0 = Start bit was not detected last
R/W: Read/Write Information bit (I
Holds the R/W bit information following the last address match and is only valid from address
match to the next Start bit, Stop bit or ACK bit.
1 = Read
0 = Write
UA: Update Address bit (10-bit I
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
Receive (SPI and I
1 = Receive complete, SSPBUF is full
0 = Receive not complete, SSPBUF is empty
Transmit (in I
1 = Transmit in progress, SSPBUF is full (8 bits)
0 = Transmit complete, SSPBUF is empty
Legend:
R = Readable bit
-n = Value at POR

C mode:
R/W-0
Note:
Note 1: This bit is cleared when the SSP module is disabled (i.e., the SSPEN bit is cleared).
