Function
DMA Request Transmitter
(channel A/channel B)
The transmitter of ESCC2 requests a
DMA transfer by activating this line. The
request remains active as long as the
respective Transmit FIFO requires data
transfers.
The amount of data bytes to be
transferred from the system memory to
the ESCC2 (= byte count) must be written
first to the XBCH, XBCL registers.
Always blocks of data (n
REST,
n = 0, 1, …) are transferred ‘till the Byte
Count is reached.
DRTn is deactivated with the beginning of
the last write cycle.
DMA Request Receiver
(channel A/channel B)
The receiver of ESCC2 requests a DMA
transfer by activating this line. The
request remains active as long as the
corresponding Receive FIFO requires
data transfers, thus always blocks of data
are transferred.
DRRn is deactivated immediately
following the falling edge of the last read
cycle.
