8.4.6 Block Transfer Mode
In block transfer mode the A and B channels are combined. One block of a specified size is
transferred per request. A designated number of block transfers are executed. Addresses are
specified in MARA and MARB. The block area address can be either held fixed or cycled.
Table 8-10 indicates the register functions in block transfer mode.

MARA:
MARB:
ETCRA: Execute transfer count register A
ETCRB: Execute transfer count register B
The source and destination addresses are both 24-bit addresses. MARA specifies the source
address. MARB specifies the destination address. MARA and MARB can be independently
incremented, decremented, or held fixed as data is transferred. One of these registers operates as a
block area register: even if it is incremented or decremented, it is restored to its initial value at the
end of each block transfer. The TMS bit in DTCRB selects whether the block area is the source or
destination.
