write ADR_20 0x20 write CR_20 40 write CR_AA 0x01 write ADR_AA AA write IER_AA 0x04

write RC_FIFO_PIRQ_20 0x0 write DTR_AA 0x0

write CR_AA 0x0D -- Enables AA as master (5.9us) write IPIER_20 0x01

write DTR_20 AA

write CR_20 0x0D -- Enables 20 as master wait_for_intr(30)

read IPISR 0xD3 -- Arbitration lost (260 us) write CR_20 0x01 -- Clears interrupt
