REG22 (Low power stand-by time) [Default: 04H]

This register can define time duration of low power stand-by mode. The available setting value is 1 (10ms)

to 255 (2550ms). Default value is 4 (40ms).

“Low power stand-by time” should be longer than 30ms when 2

frequency channel mode is used. Also, it should be longer than 40ms

when 3 frequency channel mode is used.

When “Re-transmission count” (REG11) is large, data communication

is sometimes failed. Especially, if the data message is divided into

some packets, possibility of communication failure increases.

REG23 (wired-communication setting 3) (only for the headerless packet transmission mode) [Default: 00H]

Bits 7 to 5: Not used

Bit 4: Enable addition of <Cr><Lf> to the received data

0 Not add '<Cr><Lf>' to the received data (default)

1 Add '<Cr><Lf>' to the received data

This register defines availability of "<Cr><Lf>" (carriage return and line feed codes) addition to the end of

the received data when the setting value of REG03 is “FFH”.

Bits 3 to 0: Not used

REG24 (delimiter for headerless-packet transmission, Unit of sleep time duration) [Default: C1H]

Bit 7: Not used

Bit 6: Delimiter

0 Time-out

1 <Cr><Lf> (default)

This bit of the register defines the trigger of data transmission when the setting value of REG03 is “FFH”.

When the value of the bit 0 is “0”, the FDP03 starts transmission if no data packet is coming during specific

time that is defined by REG26.

Bits 5 to 2: Not used

Bit 1: Unit of sleep time duration

0 x 10ms (Default)

1 x 100ms

Bit 0: Unit of time-out time

0 x 1 ms

1 x 10 ms (Default)

The time-out time is defined by this bit and REG26.
