The E command is used to ini tiate real time execution of the Target Z80 CPU
at the desired address. Before real time execution begins, all of the Z80
CPU registers are loaded from the register' save area in system RAM and
breakpo int codes are inserted in Target memory at the addresses where
breakpoints are set. If an attempt is made to begin or continue execution
at an address which has a breakpoint set, that instruction will be executed
with the breakpoint codes not inserted, then the breakpoints will be
inserted and real time execution started.
Fonnat (1) is used to initiate execution at address "s".
Format (2) is used to continue execution fram the last breakpoint or single
step (i.e. the address in :PC is used).
Format (3) is used to automatically set a software breakpoint at the address
specified by "f". If there are already eight breakpoints set, an
error message will be printed.
