OverflowError in Python Register File

[ghost]

Depending on the Python version, the bitfield write operation generates an OverflowError:

Traceback (most recent call last):

    rdata = rdata & (~(self._rmap.REGISTER_2_DEMO_MSK << self._rmap.REGISTER_2_DEMO_POS))
              ~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This problem can be solved by adding a masking operation for the number of desired bits:

    @demo.setter
    def demo(self, val):
        rdata = self._rmap._if.read(self._rmap.REGISTER_2_ADDR)
        rdata = rdata & ((~(self._rmap.REGISTER_2_DEMO_MSK << self._rmap.REGISTER_2_DEMO_POS)) & 0xFFFFFFFF) # this here
        rdata = rdata | (val << self._rmap.REGISTER_2_DEMO_POS)
        self._rmap._if.write(self._rmap.REGISTER_2_ADDR, rdata)

To my knowledge, this occurs for Python >=3.12
This issue possibly vanishes during the ongoing re-write of the module.
