Function
DMA Acknowledge
(channel A/channel B)
A low signal on these pins informs the
ESCC2 that the requested DMA cycle
controlled via DRTA/B or DRRA/B is in
progress, i.e. the DMA controller has
achieved bus mastership from the CPU
and will start data transfer cycles (either
write or read).
In conjunction with a read or write
operation these inputs serve as Access
Enable (similar to CS) to the respective
FIFOs. If DACK is active, the input to pins
A1 … A6 is ignored and the FIFOs are
implicitly selected. A0 and BHE/BLE are
used to select byte or word access.
If not used, these pins must be connected
to
Receive Data
(channel A/channel B)
Serial data is received on these pins.
CCR2:SOC1.
Receive Clock
(channel A/channel B)
The function of these pins depends on the
selected clock mode.
In each channel, RxCLKn may supply
either
– the receive clock (clock mode 0), or
– the receive and transmit clock (clock
– the clock input for the baud rate
May be switched to TxD function via bit
V
mode 1, 5), or
generator (clock mode 2, 3).
