Notes on PWM
The PWM starts from “H” level after the PWM enable bit is set
to enable and “L” level is temporarily output from the PWM pin.
The length of this “L” level output is as follows:
n + 1
2
× f(XIN)
(s)
(Count source selection bit = “0”,
where n is the value set in the prescaler)
n + 1
f(XIN)
(s)
(Count source selection bit = “1”,
where n is the value set in the prescaler)
Notes on A/D Converter
1. Analog input pin
Make the signal source impedance for analog input low, or equip
an analog input pin with an external capacitor of 0.01
F to 1 F.
Further, be sure to verify the operation of application products on
the user side.
<Reason>
An analog input pin includes the capacitor for analog voltage
comparison. Accordingly, when signals from signal source with
high impedance are input to an analog input pin, charge and
discharge noise generates. This may cause the A/D conversion
precision to be worse.
2. A/D converter power source pin
The AVSS pin is A/D converter power source pins. Regardless of
using the A/D conversion function or not, connect it as following :
AVSS : Connect to the VSS line
<Reason>
If the AVSS pin is opened, the microcomputer may have a failure
because of noise or others.
3. Clock frequency during 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.
f(XIN) is 500 kHz or more
Do not execute the STP instruction
4. Difference between at 8-bit reading in 10-bit A/D
mode and at 8-bit A/D mode
At 8-bit reading in the 10-bit A/D mode, “–1/2 LSB” correction
is not performed to the A/D conversion result.
In the 8-bit A/D mode, the A/D conversion characteristics is the
same as 3802 group’s characteristics because “–1/2 LSB”
correction is performed.
Notes on D/A Converter
1. VCC when using D/A converter
The D/A converter accuracy when VCC is 4.0 V or less differs
from that of when VCC is 4.0 V or more. When using the D/A
converter, we recommend using a VCC of 4.0 V or more.
2. DAi conversion register when not using D/A con-
verter
When a D/A converter is not used, set all values of the DAi
conversion registers (i = 1, 2) to “0016”. The initial value after
reset is “0016”.
Notes on Watchdog Timer
Make sure that the watchdog timer H does not underflow
while waiting Stop release, because the watchdog timer keeps
counting during that term.
When the STP instruction disable bit has been set to “1”, it is
impossible to switch it to “0” by a program.
Notes on RESET Pin
Connecting capacitor
In case where the RESET signal rise time is long, connect a
ceramic capacitor or others across the RESET pin and the VSS
pin.
Use a 1000 pF or more capacitor for high frequency use. When
connecting the capacitor, note the following :
Make the length of the wiring which is connected to a
capacitor as short as possible.
Be sure to verify the operation of application products on the
user side.
<Reason>
If the several nanosecond or several ten nanosecond impulse
noise enters the RESET pin, it may cause a microcomputer
failure.
Notes on Low-speed Operation Mode
1. Using sub-clock
To use a sub-clock, fix bit 3 of the CPU mode register to “1” or
control the Rd (refer to Figure 98) resistance value to a certain
level to stabilize an oscillation. For resistance value of Rd,
consult the oscillator manufacturer.
Fig 98. Ceramic resonator circuit
<Reason>
When bit 3 of the CPU mode register is set to “0”, the sub-clock
oscillation may stop.
2. Switch between middle/high-speed mode and low-
speed mode
If you switch the mode between middle/high-speed and low-
speed, stabilize both XIN and XCIN oscillations. The sufficient
time is required for the sub clock to stabilize, especially
immediately after power on and at returning from stop mode.
When switching the mode between middle/high-speed and low-
speed, set the frequency on condition that f(XIN) > 3
× f(XCIN).
Quartz-Crystal Oscillator
When using the quartz-crystal oscillator of high frequency, such
as 16 MHz etc., it may be necessary to select a specific oscillator
with the specification demanded.
XCIN
XCOUT
CCIN
CCOUT
Rd
Rf
