Signal ‘End of Transfer’ at end of current block only of C=0
Always signal ‘End of Transfer’ at end of current block.
C
read 0: Perform no chaining
read 1: Perform chaining using the value of “next Instruction” field as pointer
write 0: Perform no chaining even if defined by current DMA instruction
write 1: Perform chaining as defined by current instruction
Next
Inst
These 6 bits give the number of the next instruction to be executed. If the number is 3C, 3D, 3E or 3F, then the DMA
transfers will stop with the current block.
5.2 BLOCK LENGTH
This readable and writable 16-bit word gives the number of words to be transferred for the current DMA block.
5.3 AREA 1 AND 2 BASE ADDRESSES
These registers hold the addresses of the first word of memory or IO to be transferred (ie. when the channel is decrementing
the address, this register holds the highest address to be transferred.)
