| Short Description | SpecDrum port 0xDF / DAC A+D mirror, read current I2S LSB |
This port can be used to generate mono audio using the copper.
Write:
bits 7:0 = 8-bit sample written to DACs A and D (soft reset = $80)
Read:
bits 7:0 = LSB of last I2S (Pi:NextPi) sample read from DAC B (left) mirror Register ($2C) or DAC C (right) mirror Register ($2E)
