5 PERIPHERAL CIRCUITS AND
THEIR OPERATION
The peripheral circuits of the S1C88848 is interfaced with the CPU by means of the memory mapped
I/O method. For this reason, just as with other memory access operations, peripheral circuits can be
controlled by manipulating I/O memory. Below is a description of the operation and control method for
each individual peripheral circuit.

1When 1/8 or 1/17 duty has been selected by mask option, setting of this register becomes invalid.
Note) When debugging using the S1C88 Family debugging tools ICE (S5U1C88000H5) and
Peripheral Circuit Board (S5U1C88000P), all the interrupts including NMI are disabled
until values are written to addresses "00FF00H" and "00FF01H".
