Input buffers are Schmitt Triggers when in I/O or CCP/ECCP modes and TTL buffers when in System Bus
or PSP Control modes.
Valid for all PIC18F6525/6621 devices and PIC18F8525/8621 devices when ECCPMX is set. Alternate
assignments for P1B/P1C/P3B/P3C are RH7, RH6, RH5 and RH4, respectively.
Valid for all PIC18F6525/6621 devices and PIC18F8525/8621 devices in Microcontroller mode when
CCP2MX is not set. RC1 is the default assignment for ECCP2/P2A for all devices in Microcontroller mode
when CCP2MX is set; RB3 is the alternate assignment for PIC18F8525/8621 devices in operating modes
except Microcontroller mode when CCP2MX is not set.
This register is unused on PIC18F6525/6621 devices and reads as ‘0’.
Enabled only in Microcontroller mode for PIC18F8525/8621 devices.
