Table 16−Table 19 list the active level and timing option bit settings of the data output format. MCLK
clock rate is defined by option bit MCK1−0. The duration between each word, Tint, and the duration
between each byte, Tudi, are defined by option bit UDI1−UDI0. Option bit MCKEG defines MCLK active
edge. MCKI, MSGI and MDAI option bits set MCLK, MSGVAL and MDATA pin initial and active state.
The output sequence of MDATA pin is SIW, CMW, MDW0, MDW1...MDWn, EDW for all the message
types except long message. For long message, an extra AIW is added between CMW and MDW0.
Please refer to Summary of Data Output Format for different paging message format.
