The command register specifies the address of the target register for subsequent read and write operations.
This register contains eight bits as described in Table 3 and defaults to 00h at power on.
2. Only the Send Byte Protocol should be used when clearing interrupts.
the TCS3404/14 SMBus read/write protocol requires a Byte Count. All eight ADC Channel Data Registers (10h through 17h) can
be read simultaneously in a single SMBus transaction. This is the only 64-bit data block supported by the TCS3404 SMBus protocol.
The TRANSACTION field must be set to 10, and a read condition should be initiated with a COMMAND CODE of CFh. By using
a COMMAND CODE of CFh during an SMBus Block Read Protocol, the TCS3404 device will automatically insert the appropriate
Byte Count (Byte Count = 8) as illustrated in Figure 16. A write condition should not be used in conjunction with the 0Fh register.

C block transaction will continue until the Master sends a stop condition. See Figure 16 and Figure 17. Unlike the I
