SMP
SMP: SPI Data Input Sample bit
SPI Master mode:
1 = Input data sampled at end of data output time
0 = Input data sampled at middle of data output time
SPI Slave mode:
SMP must be cleared when SPI is used in Slave mode
In I
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: SPI Clock Edge Select bit (SPI mode only)
In SPI Master or Slave mode:
1 = Transmit occurs on transition from active to Idle clock state
0 = Transmit occurs on transition from Idle to active clock state
In I
1 = Enable input logic so that thresholds are compliant with SMBus specification
0 = Disable SMBus specific inputs
D/A: Data/Address bit (I
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
(I
1 = Indicates that a Stop bit has been detected last (this bit is ‘0’ on Reset)
0 = Stop bit was not detected last
S: Start bit
(I
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 bit information (I
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.
In I
1 = Read
0 = Write
In I
1 = Transmit is in progress
0 = Transmit is not in progress
UA: Update Address bit (10-bit I
1 = Indicates that the user needs to update the address in the SSP1ADD register
0 = Address does not need to be updated
BF: Buffer Full Status bit
Receive (SPI and I
1 = Receive complete, SSP1BUF is full
0 = Receive not complete, SSP1BUF is empty
Transmit (I
1 = Data transmit in progress (does not include the ACK and Stop bits), SSP1BUF is full
0 = Data transmit complete (does not include the ACK and Stop bits), SSP1BUF is empty
