PIC24FV32KA304 Datasheet, PDF (179/322 Pages) Microchip Technology – 20/28/44/48-Pin, General Purpose, 16-Bit Flash Microcontrollers with XLP Technology

PIC24FV32KA304 FAMILY
REGISTER 17-2: 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 detected.
bit 2
R/W: Read/Write Information bit (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 I²C device address byte.
bit 1
RBF: Receive Buffer Full Status bit
1 = Receive is complete, I2C1RCV is full
0 = Receive is not complete, I2C1RCV is empty
Hardware is set when I2C1RCV is written with received byte; hardware is clear when software reads I2C1RCV.
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 I2C1TRN; hardware is clear at completion of data transmission.
