DATA OUTPUT CONTROL
When the chip detects the proper address, the chip will first activate ADRVAL pin to inform the µC and
then send the de-interleaved paging message and related system information to the µC through MCLK
and MDATA pin. The format and timing of the data output is shown in Figure 12. The data output is
packed into a 3-byte word format. The function of each word is defined by the Function Code, the first
4 bits of byte3, as shown in Table 15. The format of the rest 20 bits will depend on the function code.
