80C154/83C154

Figure 6. External Drive Configuration.

Hardware Description

Same as for the 80C51, plus a third timer/counter :

EXEN2 = 0, then when Timer 2 rolls over it does not only

set TF2 but also causes the Timer 2 register to be reloaded

with the 16 bit value in registers RCAP2L and RCAP2H,

which are preset by software. If EXEN2 = 1, then Timer

2 still does the above, but with the added feature that a

1-to-0 transition at external input T2EX will also trigger

the 16 bit reload and set EXF2.

Timer/Event Counter 2

Timer 2 is a 16 bit timer/counter like Timers 0 and 1, it

can operate either as a timer or as an event counter. This

is selected by bit C/T2 in the Special Function Register

T2CON (Figure 1). It has three operating modes :

“capture”, “autoload” and “baud rate generator”, which

are selected by bits in T2CON as shown in Table 2.

The auto-reload mode is illustrated in Figure 8.

In the capture mode there are two options which are

selected by bit EXEN2 in T2CON; If EXEN2 = 0, then

Timer 2 is a 16 bit timer or counter which upon

overflowing sets bit TF2, the Timer 2 overflow bit, which

can be used to generate an interrupt. If EXEN2 = 1, then

Timer 2 still does the above, but with the added feature

that a 1-to-0 transition at external input T2EX causes the

current value in the Timer 2 registers, TL2 and TH2, to

be captured into registers RCAP2L and RCAP2H,

respectively. In addition, the transition at T2EX causes bit

EXF2 in T2CON to be set, and EXF2, like TF2, can

generate an interrupt.

The capture mode is illustrated in Figure 7.

In the auto-reload mode there are again two options,

which are selected by bit EXEN2 in T2CON.If
