EXAMPLE OF USE (CSYNC)
The MSM82C84A-2 1/3 frequency divider counter is unsettled when the power is switched
on. Therefore, the CSYNC pin has been included to synchronize CLK with another signal.
When CSYNC is at high level, both CLK and PCLK are high-level outputs. If CSYNC is then
switched to low level, CLK is output from the next input clock rising edge, and is divided
by 3.
If CSYNC has not been synchronized with the input clock, use the following circuit to
achieve the required synchronization

NOTES ON USE
The MSM82C84A-2 cannot be used if the MSM80C86A-10 or MSM80C88A-10 is used within the
range of 8 MHz < operating frequency 10 MHz.
