Shaded locations are unimplemented, read as ‘0’. Note 1: The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<12:8>, whose contents are transferred to the upper byte of the program counter. 2: These registers can be addressed from any bank. 3: Accessible only when SSPM<3:0> = 1001. 4: Accessible only when SSPM<3:0> 1001. 5: This bit is always ‘1’ as RE3 is input only. |
