一.产品概述IEV嘉泰姆

         The CX8PU86LV  CXUS7719 has program memory size greater 2K works, but the CALL and GOTO instructions only have a 11-bits address range. This 11-bit address range allows a branch within a 2K program memory page size. To allow CALL and GOTO instructions to address the entire 6K program memory address range for CX8PU86LV  CXUS7719, there is another two bits to specify the program memory page. The paging bit comes from the ROMBANK[1:0] bits(PUMODE[6:5]). When doing a CALL or GOTO instruction, the user must ensure that page bit ROMBANK[1:0] are programmed so that the desired program memory page is addressed. When one of return instructions is executed, the entire 13-bit PC is POPed from the stack. Therefore, manipulation of the ROMBANK[1:0] is not required for return instructions IEV嘉泰姆
