HARDWARE
FUNCTION BLOCK OPERATIONS/ROM ORDERING METHOD
Clock signal f(X
) is obtained by externally connecting a ceramic
IN
resonator.
Connect this external circuit to pins X
distance. A feedback resistor is built in between pins X
When an external clock signal is input, connect the clock source to
X
and leave X
open. When using an external clock, the maxi-
IN
OUT
mum value of external clock oscillating frequency is shown in Table
24.
