Caution Be sure to clear bits 7 to 5 to “0”.
Caution Be sure to clear bits 7 to 3, and 1 to “0”.
Notes
Remark The presence or absence of channel 0, 1 and 8 to 11 of timer I/O pins in each timer array unit
NFEN0 register 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, Operation clock (f
NFEN0 register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears NFEN0 register to 00H.
Set SNFEN10 bit to 1 to use the R
Clear SNFEN10 bit to 0 to use the alternate pins other than RxD1 pin or port function.
Set SNFEN00 bit to 1 to use the R
Clear SNFEN00 bit to 0 to use the alternate pins other than RxD0 pin or port function.

channel depends on the product. For details, see Table 6-1 Timer I/O Pins Included in Each Product
or Tables 6-3 to 6-5 I/O Pins That Can Be Selected for Channels 0, 1, and 8 to 11. For products that
do not provide timer I/O pins for channels 0, 1, and 8 to 11, only the P52/SLTI/SLTO pin can be
selected as a timer I/O pin.
