Group
For those devices in Group 2, the Analog to Digital
Converter cell will have a longer conversion time
in emulation than for the actual target device.
While the Development Kit allows you to set a
Push/Pull configuration for these ports, this is not
a supported feature on actual Group 2 target
devices.
The emulation chip’s stack is located between
addresses 0x100 and 0x17F. While those target
devices in Group 1 also have the stack in this same
location, the target devices in Group 2 have their
stack located between addresses 0x140 and
0x17F.
This discrepancy between the emulation chip and
Group 2 target devices has the following
repercussions during an emulation/debugging
session:
After a “Stack Underflow” break, the stack pointer
(i.e. the SP register) will indicate the address 0x100
(and not 0x140 as would occur with the actual
target device).
After a “Stack Overflow” break, the stack pointer
(i.e. the SP register) will indicate the address
0x13F (and not 0x17F as would occur with the
actual target device).
Note that if a Stack Overflow break is not validated,
any overflow of the stack will erase user variables
(if any) situated between addresses 0x100 and
0x13F inclusive.
