In transfer mode B, ATC1 automatically transfers one byte of data from any memory space to any other

memory space every time an ATC1 activation request occurs.

Set the source address in 18-bit memory pointer 1 (AT1MAP1H, M, L), and set the destination address

in 18-bit memory pointer 0 (AT1MAP0H, M, L).

Transfer mode B does not have an incrementing function for the memory pointers. The data transfer

executes for a fixed address.

Set the data transfer count for ATC1 in the transfer data counter (AT1TRC). The counter can be set to a

maximum of 255 transfers. The counter decrements each time ATC1 is activated. When it reaches x'00',

an interrupt (ATC1IRQ) occurs and the automatic transfer ends.
