SSPSTAT: SYNCHRONOUS SERIAL PORT STATUS REGISTER (I2C MODE)

R/W-0

R-0

SMP

CKE

D/A

R/W

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

SMP: SPI Data Input Sample Phase bit

1 = Slew Rate Control (limiting) disabled. Operating in I2C Standard mode (100 kHz and 1 MHz).

0 = Slew Rate Control (limiting) enabled. Operating in I2C Fast mode (400 kHz).

bit 6

CKE: SPI Clock Edge Select bit

This bit must be maintained clear. Used in SPI mode only.

bit 5

D/A: DATA/ADDRESS bit (I2C mode only)

1 = Indicates that the last byte received or transmitted was data

0 = Indicates that the last byte received or transmitted was address

bit 4

P: Stop bit

This bit is cleared when the SSP module is disabled, or when the Start bit is detected last.

1 = Indicates that a Stop bit has been detected last (this bit is ‘0’ on Reset)

0 = Stop bit was not detected last

bit 3

S: Start bit

This bit is cleared when the SSP module is disabled, or when the Stop bit is detected last.

1 = Indicates that a Start bit has been detected last (this bit is ‘0’ on Reset)

0 = Start bit was not detected last

bit 2

R/W: READ/WRITE bit Information

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 ACK bit.

1 = Read

0 = Write

bit 1

UA: Update Address bit (10-bit I2C mode only)

1 = Indicates that the user needs to update the address in the SSPADD register

0 = Address does not need to be updated

bit 0

BF: Buffer Full Status bit

Receive:

1 = Receive complete, SSPBUF is full

0 = Receive not complete, SSPBUF is empty

Transmit:

1 = Transmit in progress, SSPBUF is full

0 = Transmit complete, SSPBUF is empty
