APPENDIX
3.3 Notes on use
(2) AV
SS
pin
Connect a power source for the A-D converter, AV
SS
pin to the V
SS
line of the analog circuit.
(3) A clock frequency during an A-D conversion
The comparator consists of a capacity coupling, and a charge of the capacity will be lost if the clock frequency is
too low. Thus, make sure the following during an A-D conversion.
G
f(X
IN
) is 500 kHz or more .
(When the ONW pin is "L", f(X
IN
) is 1 MHz or more.)
G
Do not execute the STP instruction and WIT instruction.
3.3.4 Notes on the RESET pin
When a rising time of the reset signal is long, connect a ceramic capacitor or others across the RESET pin and
the V
SS
pin. And use a 1000 pF or more capacitor for high frequency use. When connecting the capacitor, make
sure the following :
G
Make the length of the wiring which is connected to a capacitor the shortest possible.
G
Make sure to check the operation of application products on the user side.
Reason
If the several nanosecond or several ten nanosecond impulse noise enters the RESET pin, a microcomputer may
malfunction.
3.3.5 Notes on input and output pins
(1) Fix of a port input level in stand-by state
Fix input levels of an input and an I/O port for getting effect of low-power dissipation in stand-by state, especially
for the I/O ports of the N-channel open-drain.
Pull-up (connect the port to V
CC
) or pull-down (connect the port to V
SS
) these ports through a resistor.
When determining a resistance value, make sure the following:
G
External circuit
G
Variation of output levels during the ordinary operation
*
stand-by state : the stop mode by executing the
STP
instruction
the wait mode by executing the
WIT
instruction
Reason
Even when setting as an output port with its direction register, in the following state :
G
N-channel......when the content of the port latch is “1”
the transistor becomes the OFF state, which causes the ports to be the high-impedance state. Make sure that the
level becomes “undefined” depending on external circuits.
Accordingly, the potential which is input to the input buffer in a microcomputer is unstable in the state that input
levels of an input and an I/O port are “undefined.” This may cause power source current.
(2) Modify of the content of I/O port latch
When the content of the port latch of an I/O port is modified with the bit managing instruction*, the value of the
unspecified bit may be changed.
Reason
The bit managing instruction is read-modify-write instruction for reading and writing data by a byte unit.
Accordingly, when this instruction is executed on one bit of the port latch of an I/O port, the following is executed
to all bits of the port latch.
G
As for a bit which is set as an input port : The pin state is read in the CPU, and is written to this bit after bit
managing.
G
As for a bit which is set as an output port : The bit value is read in the CPU, and is written to this bit after bit
managing.
