Appendix D
Using L15Y Silicon
The following items should be considerd when using L15Y Silicon:
Freescale Semiconductor
•
•
•
•
Do not write or read to registers which are marked “Reserved” in Table 1-1.
Fill the interrupt vector locations which are marked “Reserved” in Table 1-12. according to your
coding policies for unused interrupts
L15Y Silicon includes two analog to digital converters ATD0 and ATD1. ATD0 channels 7 to 0 are
connected to PAD07 to PAD00 and ATD1 channels 7 to 0 are connected to PAD15 to PAD08.
L15Y Silicon integrates the S12X_DBG module Version 2. L15Y Silicon integrates the
S12X_MMC module Version 2. This Version doesn’t support the following enhancement which is
available on S12X_MMC Version 3:
— S12XCPU and S12XBDM can access MCU resources which are on different target busses at
the same time. I.E S12XCPU can access XSRAM and S12XBDM can access Register Space
at the same time.
