TAS5441-Q1: TAS5441: Data Bits to set Switching Frequency inside Control Register 0x3

Chirag Patel1

Part Number: TAS5441-Q1

Tool/software:

Hello,

First row of Table 7-4 shows Data bits [D2 D1 D0] = [0 0 0] to set the Switching Frequency to 400kHz whereas on second row, when D0 = "1" , the Switching Frequency is set to 500kHz.

I think only D0 is used to set the Switching (i.e D0=0 sets it to 400kHz, D0=1 sets it to 500kHz)

In this case, the bits D1 and D2 on first row should show "-" instead of "0"

Can you please confirm?

Thanks

Hi Chirag

You are correct, set D0 to change switching frequency would be fine. D1 and D2 not useful here, also the description would make people confuse. It's better just say D2 D1 must keep the value b'00, don't change this 2 bits.

Thanks for confirming Shadow ! I suggest to put -- (instead of 0's) for D1 and D2 fields like other rows
