ERMINOLOGY
PORT
One of twelve data registers accessible via the 160-pin external
connector. These registers are 8 bits wide and are programmable to be
bi-directional. PORT is also sometimes referred to as just register.
CLK0-5
The 12 input clocks coming from the external connector.
IMMEDIATE
This is a mode of operation where the data written to the appropriate
PORT is immediately transferred to the PORT’s output.
Clocked Mode
This refers to the method of operation of a PORT. The data will be
latched out or in, with reference to a clock source.
Transparent Mode
This refers to the method of operation of a PORT. For example, if the
PORT is being used as an output, then as soon as the data is written it
will appear on the external connector. Likewise, if the PORT is being
used as an input, then the data appearing on the external connector is
immediately available to be read.
Numbers
Numbers can be received by the module in decimal, hexadecimal, octal
or binary. Numbers with no special leading characters are considered
decimal.
Hexadecimal numbers are designated with a leading #H, (i.e., #HFF is
decimal 255). Octal numbers are designated with a leading #Q, (i.e.,
#Q177 is decimal 255). Binary numbers are designated with a leading
#B, i.e., #B 11111111 is decimal 255.
