Interrupt 1 Register Status (7) (Read Only)
For all bits in this register, a “1” means the associated interrupt condition has occurred at least once
since the register was last read. A ”0” means the associated interrupt condition has NOT occurred
since the last reading of the register. Reading the register resets all bits to 0, unless the interrupt mode
is set to level and the interrupt source is still true. Status bits that are masked off in the associated
mask register will always be “0” in this register. This register defaults to 00.

clocks the AES3 transmitter, is asynchronous to the data source, this bit will go high every time
a data sample is dropped or repeated. Also, when TCBL is an input, and when the SRC is not
in use, this bit will go high on receipt of a new TCBL signal.
and OLRCK is asynchronous to the port data source, this bit will go high every time a data sam-
ple is dropped or repeated. Also, when the SRC is used, and the SRC output goes to the output

RCK frequency does not match what is set in the CLK1 and CLK0 bits.
