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).
