COUNT SOURCE GENERATOR
The 7641 Group has a built-in special count source generator,
SCSG. This generator consists of two 8-bit timers: SCSG1 and
SCSG2. The output of the special count source generator can be
used as a clock source for the timer X, serial I/O and two UARTs.
SCSG Operation
Timers SCSG1 and SCSG2 are both down count timers. When the
count reaches “0”, an underflow occurs at the next count source
rising edge and the contents of the corresponding timer latch are
loaded to the timer. The division ratio of each SCSG-x timer is
given by 1 / (n+1), where “n” is the value set to the SCSG-x timer.
The output of Timer SCSG1 is ANDed with the original clock (
φ
) to
make a count source for Timer SCSG2.
The SCSG output is Clock SCSGCLK. The frequency is calculated
as follows:
SCSGCLK =
φ
{n1 / (n1+1)}
{1 / (n2+1)}
n1: value set to SCSG1
n2: value set to SCSG2
If the SCSG1 Count Stop Bit (SCSGM1) is set to “1”, or Timer
SCSG1 is set to “0”, the SCSG1 count stops. When this happens,
the count source for Timer SCSG2 becomes
φ
.
Data Write Control
When the SCSG1 Data Write Control Bit or SCSG2 Data Write
Control Bit is set to “0”, and data is written to the SCSG-x timer;
the data is written to the corresponding latch and timer at the
same time. When that bit is set to “1”, the data is only written to
the latch.
