Ext/Status IP
The ESCC (Z80230/Z85230/L) contains a functional problem in Automatic RTS Deacti-
vation (see
This mode is intended for SDLC applications where the RTS signal from the ESCC is used
to enable a line driver in multi-drop line communications.
Before the frame transmission, RTS is asserted by an
equals 0).
After the last data bit of a frame is sent, a Transmit Underrun interrupt is requested. A
Deactivate RTS
turn off the line driver after the multiple-frame packet is sent.
On the SCC, the processor must monitor the data line to ensure that the frame has been
sent before it issues the
On the ESCC, RTS can be programmed to deactivate automatically after the frame is sent.
If the following sequence is performed, additional monitoring is not required:
1. Enable Automatic RTS Deactivation (WR7’ bit 2 equals 1).
