NOTES:
*
SFRs are bit addressable.
1. At reset, the BCR register is loaded with the binary value 0000 0a11, where “a” is the value on the BUSW pin. This defaults the address bus
size to 20 bits since the XA-G39 has only 20 address lines.
2. SFR is loaded from the reset vector.
3. All bits except F1, F0, and P are loaded from the reset vector. Those bits are all 0.
4. Unimplemented bits in SFRs are X (unknown) at all times. Ones should not be written to these bits since they may be used for other
purposes in future XA derivatives. The reset value shown for these bits is 0.
5. Port configurations default to quasi-bidirectional when the XA begins execution from internal code memory after reset, based on the
condition found on the EA pin. Thus all PnCFGA registers will contain FF and PnCFGB registers will contain 00. When the XA begins
execution using external code memory, the default configuration for pins that are associated with the external bus will be push-pull. The
PnCFGA and PnCFGB register contents will reflect this difference.
6. The WDCON reset value is E6 for a Watchdog reset, E4 for all other reset causes.
7. The XA-G39 implements an 8-bit SFR bus, as stated in Chapter 8 of the
XA User Guide. All SFR accesses must be 8-bit operations. Attempts
to write 16 bits to an SFR will actually write only the lower 8 bits. Sixteen bit SFR reads will return undefined data in the upper byte.
8. The AUXR reset value is typically 00h. If the Boot Loader is activated at reset because the Flash status byte is non-zero or because the Boot
Vector has been forced (by PSEN = 0, ALE = 1, EA = 1 at reset), the AUXR reset value will be 1x00 0000b. Bit 6 will be a 1 if the on-chip
VPP generator is running and ready, otherwise it will be a 0.
