PIC24FJ128GA310-I Datasheet, PDF (239/406 Pages) Microchip Technology – 64/80/100-Pin, General Purpose, 16-Bit Flash Microcontrollers with LCD Controller and nanoWatt XLP Technology

PIC24FJ128GA310 FAMILY
REGISTER 17-2: I2CxSTAT: I2Cx STATUS REGISTER (CONTINUED)
bit 4
P: Stop bit
1 = Indicates that a Stop bit has been detected last
0 = Stop bit was not detected last
Hardware is set or clear when Start, Repeated Start or Stop is detected.
bit 3
S: Start bit
1 = Indicates that a Start (or Repeated Start) bit has been detected last
0 = Start bit was not detected last
Hardware is set or clear when Start, Repeated Start or Stop is detected.
bit 2
R/W: Read/Write Information bit (when operating as I²C slave)
1 = Read: Indicates the data transfer is output from the slave
0 = Write: Indicates the data transfer is input to the slave
Hardware is set or clear after the reception of an I²C device address byte.
bit 1
RBF: Receive Buffer Full Status bit
1 = Receive is complete, I2CxRCV is full
0 = Receive is not complete, I2CxRCV is empty
Hardware is set when I2CxRCV is written with the received byte; hardware is clear when the software
reads I2CxRCV.
bit 0
TBF: Transmit Buffer Full Status bit
1 = Transmit is in progress, I2CxTRN is full
0 = Transmit is complete, I2CxTRN is empty
Hardware is set when software writes to I2CxTRN; hardware is clear at the completion of data transmission.

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
bit 15-10
bit 9-0
Unimplemented: Read as ‘0’
AMSK<9:0>: Mask for Address Bit x Select bits
1 = Enables masking for bit x of the incoming message address; bit match is not required in this position
0 = Disables masking for bit x; bit match is required in this position
