(15) Noise filter enable register 0 (NFEN0)
Symbol
NFEN0
Caution Be sure to clear bits 7, 5 to 3, and 1 to “0”.
NFEN0 is used to set whether the noise filter can be used for the input signal from the serial data input pin to
each channel.
Disable the noise filter of the pin used for CSI or simplified I
bit of this register to 0.
Enable the noise filter of the pin used for UART communication, by setting the corresponding bit of this
register to 1.
When the noise filter is enabled, CPU/peripheral operating clock (f
detection.
NFEN0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Set SNFEN30 to 1 to use the R
Clear SNFEN30 to 0 to use the P14 pin.
Set SNFEN10 to 1 to use the R
Clear SNFEN10 to 0 to use the SDA10, SI10, and P03 pins.
Set SNFEN00 to 1 to use the R
Clear SNFEN00 to 0 to use the SI00 and P11 pins.
