W83L951DG/W83L951FG
6.1 Turbo 8051 Core Block
The Turbo 8051 is fully instruction compatible. It features a faster running and better performance. It
improves the performance not just by running at high frequency but also reduces the machine cycle
duration from the standard 8051 period of twelve clocks to four clock cycles for the majority of
instructions. This improves performance by an average of 1.5 to 3 times. The Turbo 8051 also
provides dual Data Pointers (DPTRs) to speed up block data memory transfers.
In W83L951DG/FG, External Wakeup Source will only be controlled by external wakeup configure
register, not be influenced by internal interrupt configuration, even relevant interrupt enable or global
interrupt enable have not been set, can carry out action of wakeup chip equally.
