(74) RF initial setting register 10 to 12 (RFINI10 to RFINI12)
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 10 and RF initial setting register 11 continuously.
RF initial setting register 10 (bits 7 to 0): write data
RF initial setting register 11 (bit 7): 0
RF initial setting register 11 (bits 6 to 0): sub-address in RF
-Data read
Write RF initial setting register 10 and RF initial setting register 11 continuously.
RF initial setting register 10 (bits 7 to 0): 00H
RF initial setting register 11 (bit 7): 1
RF initial setting register 11 (bits 6 to 0): sub-address in RF
Read RF initial setting register 12 after writing RF initial setting register 10 and 11.
Caution Two bytes of RF initial setting register 10 and 11 must be written continuously (SEN signal
keeps low level).
RF initial setting register 10 to 12 are set via serial interface in 8-bit units.
RF initial setting register 10 and 11 are write only and the read values are undefined.
RF initial setting register 12 is read only and the initial value is undefined.
