The DRQTn remains high as long as the transmit FIFO requires data transfers. The amount of data bytes to be transferred from system memory to the HSCX (= byte count) must be written first to the XBCH, XBCL registers. Always blocks of data (n x 32 bytes + REST, n = 0, 1,…) are transferred till the byte count is reached. DRQTn is deactivated immediately following the falling edge of the last WR cycle. 41 VDD I Power supply + 5 V. 1 43 2 P-LCC P-MQFP |
