This is the number of channels available when the signal multiplex function on the i.MX257 is configured giving the most priority to this function.
[2]
It is possible to assign this function to Expansion Interface 1 (CON9) with the signal multiplex function on i.MX257.
[3]
It is possible to assign this function to the LCD Interface (CON11) with the signal multiplex function on i.MX257.
[4]
It is possible to assign this function to Expansion Interface 2 (CON14) with the signal multiplex function on i.MX257.
[5]
It is possible to convert this interface to the standard ARM 20 pin layout with the JTAG Conversion Cable (OP-JC8P25-00) option. For details, please
see 製製 A JTAG Conversion Cable (OP-JC8P25-00).
