The specifications of the peripheral functions (timer, serial interface, A/D
converter, etc.) are conventional when operating at V
Therefore, to select the count clock or base clock of a peripheral function, satisfy
the following conditions.
• V
• V
• V
• V
Rewrite the flash memory in the ranges of f
V as ever.
Connect the IC (Internally Connected) pin directly to V
Connect the AV
Connect the V
Regardless of the internal memory capacity, the initial value of the internal
memory size switching register (IMS) of all 78K0/KC1 products is fixed (IMS =
CFH). Therefore, set the value corresponding to each product as indicated
below.

Do not access addresses to which SFRs are not assigned.
Since RESET input makes the SP contents undefined, be sure to initialize the
SP before using the stack.
When P10/SCK10/TxD0, P11/SI10/RxD0, and P12/SO10 are used as general-
purpose ports, do not write to serial clock selection register 10 (CSIC10).
Use of a pull-up resistor can be specified for P60 to P63 pins by a mask option
only in the mask ROM versions.
In the case of a 1-bit memory manipulation instruction, although a single bit is
manipulated, the port is accessed as an 8-bit unit. Therefore, on a port with a
mixture of input and output pins, the output latch contents for pins specified as
input are undefined, even for bits other than the manipulated bit.
