Errata Sheet SAB 82538H, Version V2.2
1. General
The following errata should be noted when version 2.2 of the ESCC8 (SAB 82538) is
used.
a. In clock mode the RTS signal is deactivated after the transmission of the second last
bit (instead of the last) of a closing flag (or the last character of a block of characters),
if that second last bit is the last bit of the a time-slot “window”. In other words, RTS is
inactive during the transmission of the last bit, transmitted in the next time-slot
window. See figure below.
Furthermore, the ALLS (All Sent) interrupt status is generated after the transmission
of the second last bit, one clock period after the deactivation of RTS.
