TPS65311-Q1: SPI code example

Sakthi Sundaram

Part Number: TPS65311-Q1

I am using TPS65311-Q1 with TMS570LS1224PGE device.

Can I please get a PMIC SPI code example for TMS570/ any MCU device?

Hello,

We do not have SPI code example for this device. But datasheet provides all the information necessary for implementing the SPI code.

When I want to read data from SPI_SCK_FAIL register what bits do i need to send in the place of data bits?

As it have been said that 16bits (CMD_ID,parity bit and data bit) have to been for successful transmission.

Also can you tell me how to compute the parity bit?

SPI_SCK_FAILregister address (CMD_ID) is 0x03 and you need to read this address. Data write to this register is "d.c" (dont care).

It is odd parity which is calculated using bit : R/W, CMD_ID[5:0], DATA[7:0].

Below statement is available in the datasheet.

"1 bit parity (odd) (parity is built over all bits including: R/W, CMD_ID[5:0], DATA[7:0])"
