Part Number: LMX2594EVM
Other Parts Discussed in Thread: USB2ANY

Tool/software:

Hello,

I am controlling the LMX2594EVM with TICS Pro. When I select [Raw Registers: Read All Registers] in TICS Pro, all the data appears as [0x000000].Please tell me how to read back all the registers.

Best regards,

Hi Umetsu-san,

To read back, we need to configure the MUXout pin as serial data output, set MUXOUT_LD_SEL to 0.

Hi ,Noel

I set [MUXOUT_LD_SEL] to [Readback] and turned [OFF] the evaluation board's DIP SW [2: Lock indicator]. Now all registers are showing [0x002478].

Hi Umetsu-san,

0x00 2478 is register R0, to read back all register, click Read All Registers.

Hi Umetsu-san,

Try this.

Keep the DIP switch in the default position (top).

Connect the EVM to 3.3V supply.

Connect the EVM to USB2ANY.

Power up the EVM, the current is approx. 150mA.

Run TICS Pro, make sure TICS Pro can detect the USB2ANY.

Change MUXOUT_LD_SEL to Readback. Current will jump to approx. 240mA

Click Read All Registers

You should be able to read back the silicon default value.

Hi Noel, thank you for the detailed explanation.
I can reproduce up to [Change MUXOUT_LD_SEL to Readback. Current will jump to approx. 240mA], but [Click Read All Registers] sets all registers to [0x002478].
