Table 5
Table 6 Description of AUXR1 of bits
User software should not write 1s to reserved bits. Theses bits may be used in future 8051 family products to invoke
new features. In that case, the reset or inactive value of the new bit will be logic 0, and its active value will be logic 1. The
value read from a reserved bit is indeterminate. The reset value of AUXR1 is (000000xB).
