PROGRAMMING THE THS6226

Programming of the THS6226 is realized through a serial interface (pins 4 and 5) and proceeds in the following

sequence.

Two start bits are required B0 = 0 followed by B1 = 1.

B2 through B9 are used to program the THS6226.

Refer to Table 1 for the bit descriptions.

B10 (refer to Table 2) is the parity bit that controls if the word is or is not loaded.

B11 is the stop bit and should be set to B11 = 1. Figure 21 shows the sequence to be adopted.
