ADSP-2186

The ADSP-2186 package pinout is shown in the table below. Pin names in bold text replace the plain text named functions when

Mode C = 1. A + sign separates two functions when either function can be active for either major I/O mode. Signals enclosed in brackets [ ] are state bits latched from the value of the pin at the deassertion of RESET.
