CHANNEL INPUT PAGE (PAGE 3)
Page 3 is used to enter input data in the parallel mode (see PARALLEL_A,B,C and D in address of the IO control page).
ADDRESSES 16 to 31: Channel Inputs
The CHAN_INPUT_READY and CHAN_MISSED control bits in the status register (address 14) can be used as “handshake”
signals between the chip and the external processor providing the data. The external processor sets CHAN_INPUT_READY
after it has loaded the channel inputs into page 3. The chip will then clear CHAN_INPUT_READY when it has used the new
inputs. The external processor can monitor CHAN_INPUT_READY to determine when it is time to load new inputs. If the external
processor has not set CHAN_INPUT_READY when the chip wants to use the inputs, then it will set CHAN_MISSED to let the
external processor know that a handshake error has occurred and input samples have been missed.
The external processor can also use the CHREQ output as an interrupt to know new samples are needed.
