When all was new and the '51 was steam-driven (HMOS was hot) there were articles about organizing your subroutines in "levels" and using a separate bank for each level "to save push and pop time".] I can understand that in the context of ISRs but how is that an advantage in regular subroutines? You normaly pass values to a subroutine in registers so if the subroutine immediately switches banks you have lost the passed parameters. Or is this a version of the register overlaying that the Keil compiler does for example? Ian |
