DESCRIPTION
CHAPTER 3. MASTER RESET AND PROGRAM RESET
1. MASTER RESETTING
2. PROGRAM RESETTING
(INITIALIZATION)
Master resetting clears the entire memory and resumes initial values.
Master resetting can be accomplished by using the following procedure:
This resetting resumes the initial program without clearing memory.
Procedure A:
1) Plugin the AC cord to the wall outlet.
This resetting can be operated at below sequence in PGM mode.
2) Set the mode switch to REG position.
Procedure:
1) Unplug the AC cord from the wall outlet.
3) Let the ECR be witout the memory backup battery.
2) Wait over 1 muinite for discharging.
4) Unplug the AC cord from the wall outlet.
3) Set the mode switch to the PGM position.
5) Wait over 1 minute for discharging.
4) While holding down the FEED key, plugin the AC
cord to the wall outlet.
6) Plugin the AC cord to the wall outlet.
Note: In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed after the power has been restored.
The master reset can also be accomplished in the following case.
In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed
after the power has been restored.
(This is because if power failure occurs with no battery attached to
the machine, all the memories are lost and the machine does not
work properly after power recovery; this requires the master reset
operation.)

Two oscillators are connected to the CPU.
The basic clock X2 is supplied from a 12MHz oscillator.
If the CPU was not operating properly, the signal does not appear on
this line in most cases.
The sub-clock X1 generates 32.768KHz which is primarily used to
update the internal RTC (real time clock).
During the standby mode, it keeps oscillating to update the clock and
monitoring the power recovery.

CHAPTER 6. IPL (INITIAL PROGRAM LOADING) FUNCTION
The application program of the XE-A202 is written into the Flash ROM
in the CPU.
<IPL software on PC>
7) Copy the following files in "PosUtilityTool3" into the hard disk of PC.
Since the CPU supplied as a service part does not include the application program in it, the application program must be written when the
CPU is replaced with a new one.
Postool3.exe
A202v.ROM
To write the application program into the Flash ROM, connect the PC
and the XE-A202 with an RS-232C cable, and execute the PC software.
8) Boot "Postool3.exe."
*Use a D-Sub 9pin cross cable employed in conventional communication between ECR-ECR (See APPENDIX: RS232C CABLE).
