Outline of Tests
1.
MCS (PLLP2) test
Reg. (00, 0f, 10, 16) of PLLP2 is read and written for
comparison check. Reg.12 (Ver.) is read and displayed.
A0..A4 and D0..D15 are checked.
Reg.12 cannot be checked automatically because it is a
read only Reg.
Example of execution screen
MCS(PLLP2)
OK
When testing starts, "testing..." appears on the screen.
"OK" is displayed when the MCS test ends with a
satisfactory result and "NG" when it ends with an
