Timer 2 Output Enable bit.
DCEN
T2MOD.0
Down Count Enable bit. When set, this allows Timer 2 to be configured as an up/down
counter.
User software should not write 1s to reserved bits. These 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 0, and its active value will be 1. The value read from a reserved bit is
indeterminate.
