In the HT49 series of MCUs what is the correct way to change the contents of BANK 1?
Answer This can be done by using the MP1/IAR1 register pair to access the contents of BANK1. The Bank Pointer BP, must first be set to the value BP = 01H before MP1/IAR1 is used to access BANK1. It must be noted that within the HT49 series of devices, there are two memory pointers MP0 and MP1, which have corresponding Indirect Addressing Registers IAR0 and IAR1, which are used together as pairs: MP0/IAR0 (00H) and MP1/IAR1 (02H).
