SSPSTAT: SYNC SERIAL PORT STATUS REGISTER (ADDRESS: 94h)
bit 7
SMP : 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 (Figure 9-2, Figure 9-3 and Figure 9-4)
SPI mode:
For CKP = 0
1 = Data transmitted on rising edge of SCK
0 = Data transmitted on falling edge of SCK
For CKP = 1
1 = Data transmitted on falling edge of SCK
0 = Data transmitted on rising edge of SCK
In I
1 = Input levels conform to SMBus spec
0 = Input levels conform to I
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
Logical OR of this bit with SEN, RSEN, PEN, RCEN, or ACKEN will indicate if the MSSP is in IDLE mode.
UA: Update Address (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 (I
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
