LV24010LP
No.A0466-7/18
Digital interface specification (Interface specification: reference)
(1) 3-wire bus (For communication line)
Access to the LV24010 is done through the 3-wire bus:
CLOCK
Data strobe, input to the LV24010
NR_W
Command (Write or read data), input to the LV24010
DATA
Bi-directional pin: input to the LV24010 when NR_W is high, output from the LV24010 when NR_W is low.
The LV24010 can be configured to generate interrupt through the DATA-line. When interrupt mode is selected, care
should be taken that the DATA-line connection to the application micro-controller also supports interrupt.
When the required timing window for frequency measurements is not generated by the application micro-controller, an
external clock must be connected to CLK_IN pin of the LV24010
(2) Register map (For register map)
The LV24020 registers are divided in 2 blocks:
Block 01h
Status and measurement
Block 02h
Radio Control
Block 04h
RDS control
To access a register in a block, the block must be first selected by writing the block number to the BLK_SEL register.
Block selection can be skipped for subsequent accesses to other registers in the same block.
The mapping is as follows:
