SERIAL PERIPHERAL INTERFACE

FLAGS AND DEVICE STATUS

DESCRIPTION

The table below is a summary of the device flags, I/O real

time level, device Identification, and includes examples of

SPI commands (SPI commands do not use parity functions).

They are obtained using the following commands.

This command is composed of the following:

bits 15 and 14:

• [1 1] for failure flags

• - [0 0] for I/O real time status, device identification and

CAN LIN driver receiver real time state.

• bit 13 to 9 are the register address from which the flags is

to be read.

•bit 8 = 1 (this is not parity bit function, as this is a read

command).

When a failure event occurs, the respective flag is set and

remains latched until it is cleared by a read command

(provided the failure event has recovered).
