MULTIPURPOSE PINS
12 multipurpose pins that can be used either as digital general-
purpose inputs/outputs (GPIOs) or as inputs to the 4-channel
auxiliary ADC.
Each of the 12 multipurpose pins is controlled by a 4-bit mode.
Pins can be configured as digital inputs, digital outputs, or, when
applicable, as an analog input to the auxiliary ADC. A debounce
circuit is included for use with digital inputs, and it has a range
of selectable time constants between 0.3 s and 40 s.
When the inputs or outputs are driven by the control port, the
value can be directly read or controlled by reading or writing
the addresses listed in Table 66.
Each of these registers is four bytes long and is in 5.23 format.
To write a Logic 1, the bytes written should be 0x00, 0x80, 0x00,
and 0x00. To write a Logic 0, the bytes written should be 0x00,
0x00, 0x00, and 0x00.
When the outputs are driven by the core, they are represented
as MP outputs in the SigmaStudio programming tool and are
driven directly from the DSP program in 5.23 format.
In addition, there are 12 multipurpose pin value registers that
allow the input/output data to be written to or read directly
from the control port. The corresponding addresses are listed in
Table 68. Each value register contains four bytes and can only
store one of two values: logic high or logic low. Logic high is
stored as 0x00, 0x80, 0x00, 0x00. Logic low is stored as 0x00,
0x00, 0x00, 0x00. The value of the auxiliary ADC is not stored
in these registers. The value of these registers can only be one of
two values: 0x00 0x00 0x00 0x00 (digital zero) or 0x00 0x80 0x00
0x00 (digital one). More information about the multipurpose
pins can be found in the AN-951 Application Note, Using
