12.2.3 Channel status data write
• _{For channel status data write with the modulation function, set the CCB address to 0xE9.}
• _{DI0 to DI7 are not channel status bits. Be sure to input a chip address to DI0 and DI1. Input "0" to DI2, DI3, and DI7}
because they are reserved by the system. Write length of the channel status data is determined with DI4 to DI6. This
setting is possible up to 48 bits in units of 8 bits.
• _{After CE rises, input a clock combined DI0 to DI7 and write data length to CL clock to make CE “L”. For example, if}
you write data up to the bit 15 by DI4 to DI6, CL must be 24 clocks while CE is rising. If this setting goes wrong,
correct writing is not expected.
• _{Input data is written from preamble B where CE has become "L".}
