Notes
1. User software should not write ‘1’s to reserved bits. These bits may be used in future 80C51 family products to invoke
2. Reset value is ‘xxxxxx10B’.
2000 Jul 26
Single-chip 8-bit microcontroller with CAN controller
new features. In that case, the reset or inactive of the new bit will be 0, and its active value will be ‘1’. The value read
from a reserved bit is indeterminate.
