(73) RF initial setting register 00 to 02 (RFINI00 to RFINI02)
Data read/write area with sub-address is implemented in RF block. These registers are used to set the area.
These registers consist of 24 bits.
-Data write
Write RF initial setting register 00 and RF initial setting register 01 continuously.
RF initial setting register 00 (bits 7 to 0): write data
RF initial setting register 01 (bit 7): 0
RF initial setting register 01 (bits 6 to 0): sub-address in RF
-Data read
Write RF initial setting register 00 and RF initial setting register 01 continuously.
RF initial setting register 00 (bits 7 to 0): 00H
RF initial setting register 01 (bit 7): 1
RF initial setting register 01 (bits 6 to 0): sub-address in RF
Read RF initial setting register 02 after writing RF initial setting register 00 and 01.
Caution Two bytes of RF initial setting register 00 and 01 must be written continuously (SEN signal
keeps low level).
RF initial setting register 00 to 02 are set via serial interface in 8-bit units.
RF initial setting register 00 and 01 are write only and the read values are undefined.
RF initial setting register 02 is read only and the initial value is undefined.
