This buffer is a Schmitt Trigger input when configured as the external interrupt.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
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.
This buffer is a Schmitt Trigger input when configured for CCP or SSP mode.
This buffer is a Schmitt Trigger input when configured for SPI or I
PIC16F88 only.
The CCP1 pin is determined by the CCPMX bit in Configuration Word 1 register.
ANSEL
x = unknown, u = unchanged, - = unimplemented, read as ‘0’. Shaded cells are not used by PORTB.
This value applies only to the PIC16F87.
This value applies only to the PIC16F88.
