(15) Noise filter enable register 0 (NFEN0)
Symbol
NFEN0
Caution Be sure to clear bits 7, 5, 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
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 P50 or SEGx pins.
Set SNFEN20 to 1 to use the R
Clear SNFEN20 to 0 to use the P11, SI20, SDA20 or INTP6 pins.
Set SNFEN10 to 1 to use the R
Clear SNFEN10 to 0 to use the P14, SI10, SDA10 or INTP4 pins.
Set SNFEN00 to 1 to use the R
Clear SNFEN00 to 0 to use the P80, SI00 or INTP9.
