1.17.3 Timer 1
Timer 1 is an 8-bit timer with an 8-bit reload latch and
has a pulse output option (see Figure 1.35).
T123M7 of Timer123 mode register (T123M) is the
Timer 1 and 2 Data Write Control Bit. If T123M7 is “1”,
data written to Timer 1 is placed only in the Timer 1
reload latch. The latch value is loaded into Timer 1 af-
ter Timer 1 underflows. If T123M7 is “0”, the value
written to Timer 1 is placed in Timer 1 and the Timer
1 reload latch. At reset, T123M7 is set to a “0”.
The output signal TOUT is controlled by T123M5 and
T123M6. T123M5 controls the polarity of TOUT. Set-
ting the bit T123M5 to “1” causes TOUT to start at a
low level, and clearing this bit to “0” causes TOUT to
start at a high level. Setting T123M6 to “1” enables
TOUT, and clearing T123M6 to “0” disables TOUT.
Timer Mode
Count Source:
F/8 or XCin/2
In Timer mode, each time the timer underflows, the
corresponding timer interrupt request bit is set to a
“1”, the contents of the timer latch are loaded into
the timer, and the count down sequence begins
again.
Pulse Output Mode
Count Source:
F/8 or XCin/2
Timer 1 Pulse Output mode is enabled by setting
T123M6 to “1” and T123M0 to a “0”. Each time the
Timer 1 underflows, the output of the TOUT pin is
inverted, and the corresponding Timer 1 interrupt
request bit is set to a “1”. The repeated inversion of
the TOUT pin output produces a rectangular wave-
form with a duty ratio of 50 percent. The initial level
of the output is determined by the TOUT polarity se-
lect bit (T123M5). When this bit is “0”, the output
starts from a high level. When this bit is “1”, the out-
put starts from a low level.
