Dear Champs,
I am asking this for our customer.
In TRM, it says for INTCODE, "........A CPU read will clear this field. ..... a CPU read will also clear the associated interrupt flag bit in the I2CSTR register."
Questions:
1) In our testing, we read INTCODE when using AAS interrupt only. We saw INTCODE was cleared to zero but I2CSTR.AAS was not cleared on CCS watch window.
We wonder if this is right behavior or is I2CSTR.AAS is an exception?
That is, even if INTCODE = 0x7 (AAS) can be cleared by reading INTCODE, but I2CSTR.AAS cannot be cleared.
2) For associated interrupt flag bit in the I2CSTR except AAS, they will be cleared by reading associated codes in INTCODE. Would you please confirm this?
