Application note
AN421
SCC2698A differences from the SCC2698B
2
OPCR(7) = 0
MPP1x will be a GPI or TCLK input and MPP2x
will be a GPI or RCLK input.
OPCR(7) = 1
MPPlx will be a TxRDY output and MPP2x will
be a RxRDY/ FFULL output.
TestabiIity
Pin 41 of the 64–pin DIL package was a no connect on the
SCC2698A but becomes a test input on the SCC2698B. When
using the DIL package neither CSR(7:4) nor CSR(3:O) should be
programmed to Hex E or F. These values will cause the “A” version
to attempt to use inputs that are not available in the 64-pin package
option (MPI2 and MPI3 pins) and will cause the “B” version to use
the test pin as an external baud rate clock input common to all
channels. Voltages on Pin 41 should not exceed the absolute
maximum ratings. This pin may be tied high, tied low or left open.
Literature
The SCC2698A is fully described in the “SCC2698 Octal Universal
Asynchronous Receiver/Transmitter” product specification dated
July 13, 1987. Later issues of this product specification will be
retitled SCC2698A etc. to better distinguish it from the “SCC2698B
Enhanced Octal Universal Asynchronous Receiver/Transmitter
product specification.
Application Note AN410 was originally written to support the
SCC2698A. It has been revised to AN410B and retitled to include
the SCC2698B. AN410B can be used for design of both versions of
the Octal UART.
