TPS65381A-Q1: SPI communication issue

Part Number: TPS65381A-Q1

Hi,

I am using the mentioned part with Renesas MCU.

I am sending the command "RD_DEV_ID(0x03,0x00)", "RD_DEV_REV(0x06,0x00)" or any other command to read value, but I am getting 0xA1(status of previous SPI frame), 0xFF 

(Response to the command) data.

I am sending the command in 2 bytes: 1st byte is command code and 2nd byte is as data (mostly 0x00) as mentioned in Table 5-16. SPI Data-Transfer Phase.

I also checked value of status register 3, but I am getting the same data (0xA1, 0xFF).

All these commands I am giving in iteration of 100ms.

more specifically,  what data to be transfer in SPI Data-Transfer Phase as per Table 5-16 .

Kindly guide me.
