Function Documentation

unsigned int TRD_databaseSpace	(	TRD_Control *	tcb,
		unsigned int	vol,
		unsigned int *	off,
		unsigned int *	siz
	)

Identify save/restore space in EEPROM.

Parameters:

	tcb	(in) TRD control block
	vol	(in) EEPROM bank (/mm0, /mm1 convention)
	off	(out) Offset to database in EEPROM
	siz	(out) Maximum allowed size of database in EEPROM

TRD_databaseSpace() identifies save/restore space in EEPROM.

Parameters:

	vol	TRD control block
	off	EEPROM bank (/mm0, /mm1 convention)
	siz	Offset to database in EEPROM Maximum size of database in EEPROM
