TMZ.
Low-to-high transitionindicatesthatthetimer
count register has decrementtozero. This bitmust
be cleared by user software before to start with a
new count.
ETI.
This bit, when set, enablesthe timer interrupt
(vector#3forTimer1,vector#1forTimer2)request.
If ETI=0the timer interruptis disabled.IfETI=1 and
TMZ= 1an interruptrequestis generated.
D5.
This is the timers enable bit D5. It must be
cleared to0 togetherwith aset to 1 of bit D4 to en-
able both Timer 1 and Timer 2 functions. It is not
implemented on TSCR2 register.
D4.
This is the timers enable bit D4. This bit must
be setto 1 togetherwith aclear to 0 of bitD5 to en-
able both Timer 1 and Timer 2 functions. It is not
implemented on TSCR2 register.

The TSCR1 and TSCR2 registers are cleared on
reset. The correct D4-D5 combination must be
written in TSCR1 by user’s software to enable the
operation of Timer 1 andTimer 2.
