CONFIGURATION REGISTERS
Table 4 describes the Configuration Register 1 (CR1).

- R/W controls the 3 registers access (read or write):
0 = Write CR1, CR2 ,CR3,
1 = Read CR1, CR2, CR3.
- CF defines the Carrier Frequency as shown onTable 5.
Table 5: Carrier Frequency selection
CF Selected Frequency
0
315MHz
1
434MHz
- MOD sets the data Modulation type:
0 = On/Off Keying (OOK) modulation,
1 = Frequency Shift Keying (FSK) modulation.
- SOE enables the Strobe Oscillator:
0 = Disabled,
1 = Enabled,
Whatever SOE value has been programmed, a high level on STROBE sets the circuit into run mode.
- SR0/SR1 define the Strobe Ratio (SR) as shown on Table 6. SR is the ratio Sleep time over Run time and
Run time=TStrobe (where TStrobe is the Strobe oscillator period).

- DME enables the Data Manager:
0 = Disabled,
1 = Enabled (to be combined with MOD=1).
Data are output on MOSI and the associated clock on SCLK.
- HE defines if a Header word is present (the bit HE is only active if DME=1):
0 = No header,
1 = Header.
Configuration Register 2 (CR2) defines the Identifier (ID) word content. The bits will be Manchester coded.
