or
STOP. This instruction turns off the internal clock and external crystal oscillation and
reduces the standby current to 10 microamperes or less. STOP Mode is terminated by one
of the following resets: either by WDT time-out, POR, a Stop Mode Recovery Source,
which is defined by the SMR register or external reset. This causes the processor to restart
the application program at address 000Ch.
Port Configuration Register (PCON). The PCON register configures the ports individu-
ally; comparator output on Port 3, open-drain on Port 0 and Port 1, low EMI on Ports 0, 1,
2 and 3, and low EMI oscillator. The PCON register is located in the expanded register file
at Bank F, location 00
