Application Circuits
R*: Depends on the required system clock frequency. (R=36k
~2M
, at VDD=1.5V)
Mask options
The following either/or options are available by
mask option which the user must select prior to
manufacture.
4-bit input ports PP and PS with or without
pull high resistors
E ach bit of PP and PS can wake up the proc-
essor from a HALT state
Output Port PA to be CMOS or open drain
NMOS
8-bit programmable timer with external clock
or internal frequency source. Thirteen inter-
nal frequency sources are available to provide
an internal clock. Note that a value of n=6
cannot be used for the devices.
Six kinds of sound clock frequency:
f
SYS
/2
m
, m=0, 1, 2, 3, 4, 5
