-
= unimplemented, read as ’0’,
Shaded locations are unimplemented, read as ’0’.
Note 1:
These registers can be addressed from either bank.
2:
The upper byte of the program counter is not directly accessible. PCLATH is a holding register for PC<12:8> whose contents
are transferred to the upper byte of the program counter.
3:
A/D not implemented on the PIC16C62B, maintain as ’0’.
4:
Other (non power-up) resets include: external reset through MCLR and the Watchdog Timer Reset.
5:
The IRP and RP1 bits are reserved. Always maintain these bits clear.
6:
On any device reset, these pins are configured as inputs.
7:
This is the value that will be in the port output latch.
