6.1 Interface options
Two user interface modes are selectable for the PLCC68 package. These interface
modes are designated as the ‘16 mode’ and the ‘68 mode’. This nomenclature
corresponds to the early 16C454/554 and 68C454/554 package interfaces
respectively.
6.2 The 16 mode interface
The 16 mode configures the package interface pins for connection as a standard
16 series (Intel) device and operates similar to the standard CPU interface available
on the 16C454/554. In the 16 mode (pin 16/68 = logic 1), each UART is selected with
individual chip select (CSx) pins, as shown in
Table 3
.
6.3 The 68 mode interface
The 68 mode configures the package interface pins for connection with Motorola, and
other popular microprocessor bus types. The interface operates similar to the
68C454/554. In this mode, the SC16C554/554D decodes two additional addresses,
A3-A4, to select one of the four UART ports. The A3-A4 address decode function is
used only when in the 68 mode (16/68 = logic 0), and is shown in
Table 4
.
