78K0R/Kx3-L CHAPTER 10 COMPARATORS/PROGRAMMABLE GAIN AMPLIFIERS (78K0R/KC3-L, KD3-L, KE3-L only)
10.4 Operations of Comparator and Programmable Gain Amplifier
10.4.1 Starting comparator and programmable gain amplifier operation
separately for each use method.
R01UH0106EJ0300 Rev.3.00
Oct 01, 2010
The procedures for starting the operation of a comparator and a programmable gain amplifier are described below,
Figure 10-9. Using the External Pin Input for the Comparator Reference Voltage (Using Only a Comparator)
Using only a comparator
• Using the external pin input for the comparator reference voltage (Figure 10-9)
• Using the internal reference voltage for the comparator reference voltage (Figure 10-10)
Using a comparator and a programmable gain amplifier (using the programmable gain amplifier output voltage as the
comparator compare voltage input)
• Using the external pin input for the comparator reference voltage (Figure 10-11)
• Using the internal reference voltage for the comparator reference voltage (Figure 10-12)
Using the programmable gain amplifier output voltage as the A/D converter analog input (Figure 10-13)
Remark
Note
There is no positive-side input pin for comparator 1 in the 78K0R/KC3-L (40-pin). Only the signal output
from the programmable gain amplifier can be used for the input voltage.
n = 0 and 1 (78K0R/KC3-L (40-pin): n = 0).
CnCTL register setting
PER1 register setting
PIM8 register setting
PM8 register setting
Wait (1 s or more)

Operation start
Start
μ
Set the PM8 register to the input mode.
Set to the digital input disable state
(use port 8 as the analog input).
Cancel the reset state of the comparator or
programmable gain amplifier and start clock
supply.
Use the CnINV bit of the CnCTL register to select
forwarding or reversing of the output. Use the
CnDFS0 to CnDFS2 bits to select the noise
elimination width.
Enable the comparator operation by setting (1)
the CnEN bit of the CnCTL register. Input to the
positive side and negative side of the comparator
from the external pin will be enabled at the same
time.
Enable the comparator output signal by setting
(1) the CnOE bit of the CnCTL register.
