DMA Mode
Prior to the data transmission, the length of the next frame to be transmitted must be
programmed via the Transmit Byte Count Registers (XBCH, XBCL). The resulting byte count
equals the programmed value plus one byte, i.e. since 12 bits are provided via XBCH, XBCL
(XBC11. . .XBC0) a frame length of 1 up to 4096 bytes (4 Kbytes) can be selected.
After this, data transmission can be initiated by command (XTF or XIF). The HSCX will then
autonomously request the correct amount of write bus cycles by activating the DRQT line.
Depending on the programmed frame length, block data transfers of
n
×
32-bytes + remainder (n = 0, 1,…128)
are requested everytime a 32-byte FIFO half (transmit pool) is empty and accessible to the
DMA controller.
