Legend: TTL = TTL input, ST = Schmitt Trigger input
Note 1:
This buffer is a Schmitt Trigger input when configured as the external interrupt.
2:
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
3:
Low Voltage ICSP Programming (LVP) is enabled by default, which disables the RB3 I/O function. LVP must
be disabled to enable RB3 as an I/O pin and allow maximum compatibility to the other 18-pin mid-range
devices.
4:
This buffer is a Schmitt Trigger input when configured for CCP or SSP mode.
5:
This buffer is a Schmitt Trigger input when configured for SPI or I
2
C mode.
