FCE Enable Switch (SW14)

The flash chip enable (FCE) switch (SW14) selects which ~AMS signals con- nect to the internal flash memory. Since the internal memory is 1 MB, only one ~AMS signal must be connected at a time. For each switch listed in Table 2-7that is turned ON, the size of available flash memory is reduced by 1 MB.

Audio Enable Switch (SW7)

The audio enable switch (SW7) disconnects the audio signals from the pro- cessor (positions 1–5) and determines how the clock for the audio circuit generates and connects (positions 6–8). Position 8 determines if the ADC is in master or slave mode. When in master mode (position 8 is ON), the ADC generates the clock. When in slave mode (position 8 is OFF), the pro- cessor generates the clock. Positions 6 and 7 connect together the transmit and receive clocks (see Table 2-8).
