whats the data memory consist of ??in PIC 16f877a

[rangerskm]

1) explain the registers in detail .
2) what are memory banks ??how is it used ??explain
3) explain SPECIAL FUNCTION REGISTERS.
4)HOW THE MOMEORY ORGANISED IN DATA MEMORY??

hi
1-Pic is based on RISC architectures and for this reason that has a lot of registers to control different functions for instance : analog to digital conversion , timers , CCP and so on.
2-memory bank are the way to manage RAM, PIC16F have four bank, and to access these bank you must use 2 bits in STATUS REGISTER to address these banks.
3-special function register are the registers that control different function on PIC MCU as described in (1),General purpose registers are used as RAM.
4-PIC mcu are based on Harvard architecture, so the DATA memory and PROGRAM memory are separated.

on what basis memory banks are selected??

It is not possible to answer your questions in 4 row's,
so Read this book with good examples...
