Function Name: INDFET

Purpose: LDA (fetvec),Y from any bank
Call address: $FF74 (hex) 65396 (decimal)
Preparation:

	Registers:	.A = pointer to address
			.X = bank (0-15)
			.Y = index
	Memory:		setup indirect vector
	Flags:		none
	Calls:		none

	Registers:	.A = data
			.X used
	Memory:		none
	Flags:		status valid

Description: INDFET enables applications to read data from any other bank. It sets up FETVEC ($2AA), calls GETCFG to convert the bank number, and JMPs to code in common (shared) RAM at $2A2 which switches banks, loads the data, restores the user's bank, and returns. When calling a non-system bank, the user should take necessary precautions to ensure that interrupts (IRQ's and NMI's) will be handled properly (or disabled beforehand).

EXAMPLE:

	LDA	#$00	;setup to read $2000
	STA	$FA
	LDA	#$20
	STA	$FB
	LDA	#$FA
	LDX	#$01	;in bank 1
	LDY	#$00
	JSR	$FF74	;LDA ($FA,RAM 1),Y
	BEQ	etc
