I2C Interrupt and Hold Enable Register
Notes:
  1. 1.Enabled interrupt flags are OR’ed to produce the PIRx[I2CxIF] bit.
  2. 2.When ACKTIE is set (ACKTIE = 1) and ACKTIF becomes set (ACKTIF = 1), if an ACK is generated, CSTR is also set. If a NACK is generated, CSTR remains unchanged.
  3. 3.When WRIE is set (WRIE = 1) and WRIF becomes set (WRIF = 1), CSTR is also set.
  4. 4.When ADRIE is set (ADRIE = 1) and ADRIF becomes set (ADRIF = 1), CSTR is also set.
