I2C0STAT is a read-only special function register (SFR) to indicate the state of the I

Initial value:
I2C0STAT
The I20ER bit is set to “0” when a write operation to I2C0CON is performed. The I20ER bit is set to “0” when the
The I20BB bit is used to indicate the state of use of the I
the I
“0” when the I20EN bit of I2C0MOD is “0”.
The I20ACR bit is used to store the acknowledgment signal received. Acknowledgment signals are received each
time the slave address is received and data transmission or reception is completed. The I20ACR bit is set to “0”
when the I20EN bit of I2C0MOD is “0”.
The I20ER bit is a flag to indicate a transmit error. When the value of the bit transmitted and the value of the SDA
pin do not coincide, this bit is set to “1”.The SDA remains the output until the subsequent byte data communication
terminates even if I20ER is set to “1”.
I20EN bit of I2C0MOD is set to “0”.
