The purpose of this test are as follows:
4-6-4. Test contents
(1) Calendar & clock setup test
This test is used to set data of calendar, clock, and alarm for the RTC.
(2) Calendar & clock real test
This test is used to read and display the calendar, clock, and alarm data
of the RTC.
(3) Timer interrupt test
This test is used to execute the update test of the RTC calendar and clock.
The following timer interrupt items are also checked:
• Periodic interrupt
• Alarm interrupt
• Update ended interrupt
(4)CMOS RAM marching test
Caution: During execution of this test, do not turn off the power and do
not reset the unit.
[Test condition setting]
• Error/Stop/Continue/1 pass
[Test contents]
The test pattern data are written into the area (Index address 0Eh - 7Eh) of
the CMOS RAM, and the read/verify test is executed.
After writing the data, the read/verify test is executed only once.
There are four kinds of data pattern to be written: 00h, FFh, 55h, and AAh.
There are four kinds of data pattern to be written: 00h, FFh, 55h, and AAh.
Writing the above four patterns form 1 pass.
Before execution of the test, save all the data in the CMOS RAM. After exe-
cution of the test, restore the data to the CMOS RAM.

(6) CMOS RAM display test
All the data in all the areas (Index address: 00h - 7Fh) of the CMOS RAM
are displayed in HEX.
(7) CMOS TRAM battery backup test
This test is used to check the RTC control register Bit 7 (VRT bit), and check
changes in the CMOS RAM setting data and the data backup battery.
(8) Error table display
For service repair, the error information is saved in the DRAM, and data
saved in the DRAM are edited and displayed. When no error is found in
the previous tests (1) ~ (7), "OK" or "NO ERROR" is displayed.
(9) Other supplementary note
In the marching test and the write/read-verify test, max. 20 errors are
recorded as the error information from selection of the function in chro-
recorded as the error information from selection of the function in chro-
nological order. No more error is recorded.
