and P32 with reference to the voltage on P33. The analog function is enabled by setting
the D1 of Port 3 Mode Register (P3M). The comparator output can be outputted from P34
and P37, respectively, by setting PCON register Bit D0 to 1 state. For the interrupt func-
tion, P30 and P33 are falling edge triggered interrupt inputs. P31 and P32 can be pro-
grammed as falling, rising or both edges triggered interrupt inputs (see

When enabling or disabling analog mode, the following is
recommended:
P33-P30 differs from the Z86C33/C43/233/243 in that there is no
