Figure 2-104. TXM Register
Read Method
When reading Timer X, the high-order byte is read first. Reading the high-order byte causes the values of
Timer XH and Timer XL to be placed in temporary registers assigned the same addresses as Timer XH and
Timer XL. The low-order byte of Timer X is then read from its temporary register. This operation assures
the correct reading of Timer X while it is counting.
2.13.1.2
Count Stop Control
If the Timer X Count Stop Bit (TXM7) (bit 7 of the TXM) is set to a “1”, Timer X stops counting
in all four modes.
2.13.1.3
Timer Mode
Count Source:
Φ
/
n
(where
n
is 8, 16, 32, or 64) or
SCSGCLK
In this 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.
2.13.1.4
Pulse Output Mode
Φ
/
n
(where
n
is 8, 16, 32, or 64) or
SCSGCLK
Count Source:
Each time the timer X underflows, the output of the CNTR0 pin is inverted, and the corresponding
Timer X interrupt request bit is set to a “1”. The repeated inversion of the CNTR0 pin output
produces a rectangular waveform with a duty ratio of 50 percent. The initial level of the output is
determined by the CNTR0 polarity select bit (bit 6). When this bit is low, the output starts from a
high level. When this bit is high, the output starts from a low level.
