PRODUCT DESCRIPTION

Q. Which of the following is not an improvement from
A. (c) No new READ register addressing is added in the

a. The ESCC has less communications channels
b. The protocols supported by ESCC and USC are
the SCC to the ESCC?
a. The ESCC has deeper FIFOs
b. The ESCC has new SDLC enhancements
c. The ESCC has added new READ Registers
d. The ESCC has added new WRITE Registers
than the USC
different
ESCC although we allowed some Write Registers
to become readable through the existing READ
Register.

A. (c) Most ESCC and USC Family members have two
The ESCC has 4 bytes of Tx FIFO and 8 bytes of Rx FIFO,
while the SCC has 1 byte for the Tx and 3 bytes for the Rx.
The ESCC has many new SDLC enhancements, such as
automatic EOM reset, automatic opening flag generation,
etc.
The ESCC has added WR7' as a new WRITE Register to
configure the new options, therefore, (a), (b), (d) are all dif-
ferences between the SCC and ESCC.

channels and protocols. Support by the SCC is a
subset of ESCC. Both ESCC and USC can sup-
port T1 data rates so (a), (b), (d) are not correct.
