Example code for accessing the MBAR is as follows:
Register D0 will contain the value of MBAR. MBAR can be read using the following code:
Address $0003FF00 in CPU space (MBAR) will be loaded with the value $FFFFF001.
This value will set the base address of the internal registers to $FFFFF. MBAR can be
written to using the following code:
4.3.2 System Configuration and Protection Registers
The following paragraphs provide descriptions of the system configuration and protection
registers.
4.3.2.1 MODULE CONFIGURATION REGISTER (MCR). The MCR, which controls the
SIM40 configuration, can be read or written at any time.
