EMULATOR FUNCTIONAL DISCREPANCIES
Extended function timers
The two Extended Function Timers work correctly on the emulator but the related
registers cannot be read using the Registers Windows, nor through the
Watch Window.
It is advised not to display the alternate counter contents using windows debugger.
If required, a workaround can be done:
When you need to verify the value of the counter, add in your program instructions
that copy the alternate counter contents in two working registers (one for the
Alternate Counter High byte, one for the Alternate Counter Low byte) (remember
that the MSB must be read first).
Display the working registers window to check the counter values.
HW0SW1 pin option
A 10 K
not connected to your application board, the default option is the software
watchdog reset.
On your application board, if you want to force a hardware watchdog reset, we
advise you to connect the HW0SW1 pin directly to GND.
Protection register and emulation chip life
The emulator uses the OTP area in the same way that the target MCU does ( or will
do, when finalized ). This means that this register can be written to only once.
Your emulator uses a chip similar to the target MCU. For the FLASH and EEPROM
memories, this means that write cycles in these areas are limited. If, after a while,
writing to memory is no longer possible for the FLASH or EEPROM areas, the
BGA144 emulation chip will have to be changed. (Note that loading application
software in system memory does not write to the FLASH area at all).
pull-up resistor has been added to the emulator. So, when the emulator is
