C.1
This chapter provides technical data about the 8051 core hardware operation and timing. The
topics are:
C.2
The 8051 core includes three timer/counters (Timer 0, Timer 1, and Timer 2). Each timer/
counter can operate as either a timer with a clock rate based on the CLK24 pin, or as an event
counter clocked by the T0 pin (Timer 0), T1 pin (Timer 1), or the T2 pin (Timer 2).
Each timer/counter consists of a 16-bit register that is accessible to software as two SFRs:
