a) Standard mode (the parameter No.8980#7=0 and #6=1)
The four trigger point of the parameter No.8981,8982,8983
and 8984 are specified under the trigger condition specified
by the parameter No.8980#0,#1,#2,#3 and #4.
The trigger can be specified as follows and the trigger point
can be specified by the addresses of 4 point or less.
1. Instruction trigger
2. Data read or write trigger
3. Data write trigger
When the trigger is broken, the content of all register and
stack are saved in RAM area of 128 byte.
The saved information can be examined by PMC “Content memory”.
The RAM address of FS16-B/C is from 0F4AE4H to 0F4B63H.
The RAM address of i series is from 5102E4H to 510363H.

When the debug is begun (parameter set operation), the head four bytes
of RAM are set to 0. It is sure to set the head four bytes of RAM
excluding 0 because debug register (DR6) is saved in the RAM when any
trigger condition is broken.
* The trigger conditions of 4 points cannot be separately
specified. The triggers of 4 points are specified the
same condition by the parameter No.8980#0,#1,#2,#3 and #4.
* The trigger conditions are specified as follows, so please
set an irrelevant numerical value in 4th trigger address not
used when you specify trigger of 1st, 2nd and 3rd point.
(In almost cases, it set 0.)
