DSP56824ADM Technical Summary
Jumper Configuration
2.6.6.3

Codec Output Connector Signal Selection

Jumper group JG17 is used to select which pins on J5 provide the output signal from the
codec. See Table 2-8 for JG17 configuration information.

1–2 (default)
2.6.6.4

Codec Output Load Selection

Jumper group JG11 is used to select the output drive capability of the codec with respect
to analog ground. See Table 2-9 for JG11 configuration information.
Note: The DSP56824ADM is factory configured for codec output of 1.7 V into a
300 Ω load.
2.6.7

RS-232 Serial Communication Configuration

The DSP56824ADM includes a DB9 connector for an RS-232 serial link. Jumpering JG7
pins 3–5 and 4–6 connects the RS-232 serial port to the DSP. Although there is no
hardware support for RS-232 on the DSP56824, software on the DSP may use the serial
port by program control of pins PB0 and PB1.
