Legend: x = unknown, u = unchanged. - = unimplemented read as '0', q = value depends on condition.
Note 1: The upper byte of the program counter is not directly accessible. PCLATH is a slave register for PC<12:8>. The contents
of PCLATH can be transferred to the upper byte of the program counter, but the contents of PC<12:8> is never transferred
to PCLATH.
2: The TO and PD status bits in the STATUS register are not affected by a MCLR reset.
3: Other (non power-up) resets include: external reset through MCLR and the Watchdog Timer Reset.
