has been read will generate a new interrupt. Interrupts that are already noted in the digital equalizer Status 0 are cleared
by reading it.
Table 24
Digital equalizer STATUS0.
Notes
1.
BKSW (filter bank switched) indicates that the last main data coefficients sent to the digital equalizer have been
activated.
Vup indicates whether an interrupt caused by the rising edge of VIRGIN has occurred.
AEup indicates whether an interrupt caused by the rising edge of AUX envelope has occurred.
AEdn indicates whether an interrupt caused by the falling edge of AUX envelope has occurred
Lup indicates whether an interrupt caused by the rising edge of LABEL has occurred.
Ldn indicates whether an interrupt caused by the falling edge of LABEL has occurred.
ECZ indicates that the AUX envelope counter has reached zero.
