SBFS030B – JANUARY 2006 – REVISED APRIL 2006
RATIO
SRC Ratio Status, Active High
The RATIO bit will be set to 1 when the input sampling rate is higher than the output sampling rate, and the RATIO interrupt is
unmasked (the MRATIO bit in control register 0x0B is set to 1). This will also cause the INT output (pin 23) to be driven low and the
SRC bit in status register 0x02 to be set to 1, indicating that an interrupt has occurred.
