INT 58 C - TI Professional PC - SYSTEM TIMER 25ms HOOK Desc: called from the hardware timer tick interrupt, after executing the first four BIOS timing events, updating the system clock, invoking INT 5A if required, saving registers, and switching to a temporary stack (the one reserved for IRQ3) Notes: the handler for this interrupt may destroy AX,BX,DI,ES but must preserve all other registers; 8 WORDs of stack space are available, of which at most 4 may be used if the handler enables interrupts if the handler switches stacks (because more than 4/8 WORDs are required), the original stack must be restored before chaining to the previous handler SeeAlso: INT 43"TI Professional",INT 4C"TI Professional" SeeAlso: INT 5A"TI Professional"Top
