TinyPowerTM A/D Flash Type 8-Bit MCU with LCD & EEPRO

Bank Pointer – BP

Depending upon which device is used, the Program and Data Memory are divided into several

banks. Selecting the required Program and Data Memory area is achieved using the Bank Pointer.

Bit 5 of the Bank Pointer is used to select Program Memory Bank 0 or 1, while bits 0~2 are used to

select Data Memory Banks 0~5.

The Data Memory is initialised to Bank 0 after a reset, except for a WDT time-out reset in the Power

Down Mode, in which case, the Data Memory bank remains unaffected. It should be noted that the

Special Function Data Memory is not affected by the bank selection, which means that the Special

Function Registers can be accessed from within any bank. Directly addressing the Data Memory

will always result in Bank 0 being accessed irrespective of the value of the Bank Pointer. Accessing

data from banks other than Bank 0 must be implemented using Indirect addressing.

As both the Program Memory and Data Memory share the same Bank Pointer Register, care must be

taken during programming.
