SSPSTAT: SYNCHRONOUS SERIAL PORT STATUS REGISTER (ADDRESS 94h)
bit 7
SMP: SPI Data Input Sample Phase bits
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:
SMP must be cleared when SPI is used in Slave mode
I
This bit must be maintained clear
CKE: SPI Clock Edge Select bits (Figure 9-2, Figure 9-3, and Figure 9-4)
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 default)
0 = Data transmitted on rising edge of SCK
I
This bit must be maintained clear
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
the START bit is detected last. SSPEN is cleared.
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
the STOP bit is detected last. SSPEN is cleared.
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
ing the last address match. This bit is only valid from the 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 (I
1 = Transmit in progress, SSPBUF is full
0 = Transmit complete, SSPBUF is empty
