Notes
1.
A pull-up resistor must be present to prevent a floating input during normal/alternative mode when no external signal is applied to the pad.
Pull-up = present internally.
All ports are in input mode after reset; that means the value at the pin is determined by the external circuitry: pull-up registers Rext (and/or external
applied input).
A pull-up resistor must be present to prevent floating (digital) inputs if the pad is used for the analog inputs ADCO, ADCI and ADC2. This pull-up is
also present if these pins are used as port function. Pull-up is internally.
These pins are standard I/O cells SPF20PGD (2 mA PP slew-rate controlled).
A pull-up resistor must be present to prevent a floating input during nominal/alternative mode when no external signal is applied to the pad.
Pull-up = present internally.
Inverse of the Bp bit (located in OSCON).
After reset the Bp bit (located in OSCON) = 1, therefore output becomes LOW.
Its pull-down resistor is present internally (see Section 13.2).
For the SDIP42 package, pin P1.0 can be exchanged for a V
SS
or V
DD
, pin P1.7 for a V
SS
.
10. For the PLCC68 package, pin P1.0 can be exchanged for a V
DD
line.
11. Output is HIGH via external resistor.
