* Initialize DMA Channel 1
***************************************************************************
* Initialize DMA channel 1 MCR
* Normal Operation, ignore FREEZE, single-address mode. ISM field at 2. Make
* sure CPU32 SR I2-I0 bits are less than or equal to ISM bits for channel startup.
* Supervisor/user reg. unrestricted, MAID field at 7. IARB priority at 1.
* Clear channel control reg.
* Clear STR (start) bit to prevent the channel from starting a transfer early.
* Initialize interrupt reg.
* Interrupt priority at 7, interrupt vector at $42.
* Initialize channel status reg.
* Clear the DONE, BES, BED, CONF and BRKP bits to allow channel to startup.
* Initialize function code reg.
* DMA space, user data space for source.
* Initialize source operand address
* Source address is equal to $10000.
* Initialize the byte transfer count reg.
* The number of bytes to be transferred is $C or 3 long words
* Channel control reg. init. and Start DMA transfers
