/*
|
|
* This is a model of the Maxim MAX1110/1111 ADC chip, which for QEMU
|
|
* is an SSI slave device. It has either 4 (max1110) or 8 (max1111)
|
|
* 8-bit ADC channels.
|
|
*
|
|
* QEMU interface:
|
|
* + GPIO inputs 0..3 (for max1110) or 0..7 (for max1111): set the value
|
|
* of each ADC input, as an unsigned 8-bit value
|
|
* + GPIO output 0: interrupt line
|
|
* + Properties "input0" to "input3" (max1110) or "input0" to "input7"
|
|
* (max1111): initial reset values for ADC inputs.
|
|
*
|
|
* Known bugs:
|
|
* + the interrupt line is not correctly implemented, and will never
|
|
* be lowered once it has been asserted.
