We have a project which need to use expended page. we have set the file of project.prm ,for example internal ram or rom,and external ram. so i need to set the option of compiler for hc12. Some freescale FAE tell us that the option "PPAGE Register is used for paging" should be set first. but the envirement shows that PPAGE Register is used for paging(enter [0xaddr|RUNTIME]) the question is that how to set this option?how to set this RUNTIME? We are directly writing "RUNTIME" into the blank.but It is failed to visit the right page which need to be visited.
