TTL = TTL input
ST = Schmitt Trigger input
Pin functions T1OSO and T1OSI are reversed on the PIC16C64.
CCP2 and the USART are not available on the PIC16C64/64A/R64.
This buffer is a Schmitt Trigger input when configured in RC oscillator mode and a CMOS input otherwise.
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.
This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel Slave
Port mode (for interfacing to a microprocessor bus).
