P6-0 to P6-3 pins have multiplexed functions for
the on-chip 6-bit 4-channel AD converter analog
input. The on-chip AD converter uses
successive approximation. The conversion time
is 242 ms when the 16.9344-MHz crystal
oscillator is used and 7 instruction cycles
(280 ms) when the 75-kHz crystal oscillator is
used. The program can specify necessary pins
for AD analog input on a per bit basis. The
