Receive Message Complete
Confirmation from CPU to ESCC2 that the current frame or data
block has been fetched following an RPF or RME interrupt, thus
the occupied space in the RFIFO can be released.
Note: In DMA Mode, this command has to be issued after an RME
Reset HDLC Receiver
All data in the RFIFO and the HDLC receiver is deleted. In
auto-mode, additionally the transmit and receive sequence
number counters are reset.
Receiver Not Ready/Transmission Repeat
The function of this command depends on the selected operation
mode (MDS1, MDS0, ADM bit in MODE):
• auto mode: RNR
• extended transparent mode 0, 1: XREP
Start Timer
The internal timer is started.
Note: The timer is stopped by rewriting the TIMR register after
H
Determines the status of the ESCC2 receiver, i.e. whether a
received frame is acknowledged via an RR or RNR supervisory
frame in auto-mode.
0 … Receiver Ready (RR)
1 … Receiver Not Ready (RNR)
If XREP is set to one together with XTF and XME (write 2A
to CMDR), the ESCC2 repeatedly transmits the contents of
the XFIFO
transparently, i.e. without FLAG, CRC or Bit Stuffing.
The cyclic transmission is stopped with an XRES command.
