Epp- Enable Printpoints - Nice Z80+ Operation Manual

EPP - ENABLE PRINTPOINTS
Printpoints are used with breakpoints to allow NICE Z80 to go through (in RUN mode)
a large number of instructions while displaying the registers only at specific addresses.
After the register display, printpoints allow program execution to continue (unlike
breakpoints which cause the processor to stop at a specified location).
