backup_sram_read()

Description

Reads from SRAM specific memory address. To use this function user must add #include <backup_sram>.

Syntax

backup_sram_read(address, variable);

Parameters

Variable	Input

Variable	Input
`address`	Any address number from 1 to 10.
`variable`	Variable onto which read value will be stored.

Returns

Return value	Return explanation
SCRIPT_OPERATION_SUCCESS	Successful SRAM read operation.
SCRIPT_OPERATION_FAILED	Failed to read from SRAM.
SCRIPT_PARAM_INVALID	Invalid parameters. This error indicates that one or more of the arguments are not valid.
