PIC24FJ64GA006-I Datasheet, PDF (143/258 Pages) Microchip Technology – 64/80/100-Pin, General Purpose, 16-Bit Flash Microcontrollers

PIC24FJ128GA010 FAMILY
REGISTER 16-2: I2CxSTAT: I2Cx STATUS REGISTER (CONTINUED)
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 bit Information (when operating as I²C slave)
1 = Read – indicates data transfer is output from slave
0 = Write – indicates data transfer is input to slave
Hardware is set or clear after 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 the software writes to I2CxTRN. Hardware is clear at the completion of
data transmission.
