Obviously there is no such option.

It's very nice to hear that somebody is extending features of ucsim.

you start ucsim with -J option, trace will be turned on, and
_every_ instruction will print out cpu state like "info reg".
Tracing can be checked and turned on/off using "jaj" command which

Hi,
I'm testing simulation of stm8 flash controller in ucsim. To start a
program/erase operation flash area must be written as data. sdcc-stm8
uses 16 bit pointers, is it possible to address over 64k somehow?

Hi,
I'm using sdcc-stm8 with following code:
struct FLASH_t { ... ; volatile uint8_t iapsr; ...};
#define FLASH ((struct FLASH_t *)BASE_ADDRESS_OF_FLASH_CONTROLLER)
Program waits end of flash operation in a busy loop:

it works well rereading value of iaps

Dear Bill,
SDCC needs a simulator too. To implement support in uCsim, we need as
much information as you can provide...

No. Wrapping is not implemented. SP is checked against a limit after
push operations, but this generates an error message only. You can set
the limit with "sp_limit=value" command, but it will not be wrapped.
