DEVELOPMENT TOOL REFERENCE MANUAL
4 NAMES AND FUNCTIONS OF PARTS
This section describes the names and functions of the parts of the S5U1C62xxxE.
4.1 Basic Functions
The S5U1C62xxxE has the following basic functions:
■ Program execution (Run function)
Install the EPROM containing the application program and execute the program.
■ Single-step program operation (Single-step function)
Programs may be run instruction by instruction to check the internal state of the CPU as it changes with
each instruction.
■ Program execution suspension at a given address (Break function)
A breakpoint may be set at an address at which it is desired to suspend program execution. After
execution has stopped at the breakpoint, it can be restarted with the program run function.
■ Displaying program addresses and instruction codes during a break
Program addresses and instruction codes may be displayed on the LED indicators.
■ Displaying the contents of RAM, registers, and flags during a break
The contents of RAM, the A, B, X, and Y registers, the stack pointers, and the flags may be displayed on
the LED indicators during a break.
■ Interface with ICE
The S5U1C62xxxE can interface with the ICE so that a higher level debugging environment may be
established.
■ Setting hardware options by installing function option and segment option ROMs
Hardware options, i.e., I/O ports and segments, can be specified by writing option data for the func-
tions created by the function option generator and the segment option created by the segment option
generator into EPROM, and installing the EPROM.

■ Switches and keys
• EN/DIS switch
This switch enables or disables the setting of
breakpoints. When the switch is in the EN
(Enable) position, the setting of breakpoints is
enabled. When it is in the DIS (Disable)
position, the setting of breakpoints is
disabled. Normally, set the switch to the DIS
position.
