TIMERS
The 7630 group has five timers: two 16-bit timers and three 8-bit
timers . All these timers will be described in detail below.
16-bit Timers
Timers X and Y are 16-bit timers with multiple operating modes.
Please refer to Fig. 17.

φ is internal system clock)
Timer X
Timer X is a 16-bit timer with a 16-bit reload latch supporting the fol-
lowing operating modes:
(1) Timer mode
(2) Bi-phase counter mode
(3) Event counter mode
(4) Pulse width measurement mode
These modes can be selected by the timer X mode register (TXM).
In the timer- and pulse width measurement mode, the timer’s count
source can be selected by the timer X count source selection bits of
the timer Y mode register (TYM). Please refer to the Figures below
for the TXM and TYM bit assignment.
On read or write access to timer X, note that the high-order and low-
order bytes must be accessed in the specific order.
Write method
When writing to the timer X, write the low-order byte first. The data
written is stored in a temporary register which is assigned to the
same address as TXL. Next, write the high-order byte. When this is
finished, the data is placed in the timer X high-order reload latch
and the low-order byte is transferred from its temporary register to
the timer X low-order reload latch. Depending on the timer X write
control bit, the latch contents are reloaded to the timer immediately
(write control bit = “0”) or on the next timer underflow (write control
bit = “1”).
Read method
When reading the timer X, read the high-order byte first. This
causes the timer X high- and low-order bytes to be transferred to
temporary registers being assigned to the same addresses as TXH
and TXL. Next, read the low-order byte which is read from the tem-
porary register. This method assures the correct timer value can be
read during the timer count operation.
Timer X count stop control
Regardless of the actual operating mode, timer X can be stopped
by setting the timer X count stop bit (bit 7 of the timer X mode regis-
ter) to “1”.
