68 MODE
DESCRIPTION
The ST16C454 is a universal asynchronous receiver
and transmitter (UART) with a dual foot print interface.
The 454 is an enhanced UART with data rates up to
1.5Mbps and software compatible to ST16C450.
Onboard status registers provide the user with error
indications, operational status, and modem interface
control. System interrupts may be tailored to meet user
requirements. An internal loop-back capability allows
onboard diagnostics. The ST16C454 offer an additional
68 mode which allows easy integration with Motorola,
and other popular microprocessors. The 454 combines
the package interface modes of the ST16C454 on a
single integrated chip with a selection pin.
