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
2
C mode:
This bit must be maintained clear
CKE:
SPI Clock Edge Select bit
SPI mode, CKP = 0:
1
= Data transmitted on rising edge of SCK (Microwire alternate)
0
= Data transmitted on falling edge of SCK
SPI mode, CKP = 1:
1
= Data transmitted on falling edge of SCK (Microwire alternate)
0
= Data transmitted on rising edge of SCK
I
2
C mode:
This bit must be maintained clear
D/A:
Data/Address bit (I
2
C mode only)
In I
2
C Slave mode:
1
= Indicates that the last byte received was data
0
= Indicates that the last byte received was address
P:
STOP bit
(1)
(I
2
C mode only)
1
= Indicates that a STOP bit has been detected last
0
= STOP bit was not detected last
S:
START bit
(1)
(I
2
C mode only)
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
2
C mode only)
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
2
C 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
Receive (SPI and I
2
C modes):
1
= Receive complete, SSPBUF is full
0
= Receive not complete, SSPBUF is empty
Transmit (In I
2
C mode only):
1
= Transmit in progress, SSPBUF is full (8 bits)
0
= Transmit complete, SSPBUF is empty
bit 6
bit 5
bit 4
bit 3
bit 2
bit 1
bit 0
Note 1:
This bit is cleared when the SSP module is disabled (i.e., the SSPEN bit is cleared).
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
