7.5 General Purpose Outputs (GPOUT)
There are seven general purpose outputs. The signal level on each output is con-
trolled by one of several sources (see below). The electrical characteristic of these out-
puts is shown in the following list.
GPOUT0, GPOUT1, GPOUT2 - Differential (LVDS) outputs
GPOUT3, GPOUT4 - Single ended TTL level outputs
GPOUT5 - Open collector
GPOUT6 - Open collector
The source for each GPOUT bit is controlled by the corresponding GPOUTx_CON bit-
field. These are located in CON8. The source for each GPOUT can be programmed
independently of the others. Table 7-1 shows the sources for each GPOUT.
7.5.1 The Open Collector Drivers for GPOUT5 and GPOUT6
GPOUT5 and GPOUT6 are open collector drivers. Figure 7-3 shows the GPOUT5 and
GPOUT6 driver circuits and their associated jumpers for various configurations.
???[how to handle difference between boards?] The board is shipped in with JP2 in
position 1-2, JP4 in position 1-2, no jumpers in JP1 and JP3.
