multi controller manual

Ver1.00

■Summary

The multi-controller is a controller that maintains compatibility with the conventional Saturn standard pad, but enables digital crosshair + 6 buttons + 4-axis analog operation in a unique mode.
Most commercially available software can also be operated as a standard pad by switching modes. Additionally, various functions can be added by replacing the plug unit with the controller's expansion socket. (Currently, expansion unit is undecided)

This text explains the data format when a normal unit is attached to an expansion unit.

■Digital/analog common specifications

●When power is turned on

When the power is turned on, the analog key position is corrected to the center value (128,128), and the trigger position is corrected to the 0 value.

●Mode switch

The mode switch performs digital/analog switching and has the following functions.

Data format switching to maintain compatibility with Saturn standard pads.

Center position (128,128) correction of analog value and 0 (zero) value correction of L/R trigger.

●Character code of compatible peripheral: Multi-controller = “E”

This is the character code written in SYSTEMID in the application CD-ROM.

■Digital mode

Digital mode data format

	bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0
Peripheral ID	0	0	0	0	0	0	1	0
1st data	Right	Left	Down	Up	Start	ATRG	CTRG	BTRG
2nd data	RTRG	XTRG	YTRG	ZTRG	LTRG	1	1	1

●Saturn peripheral ID = 02H

Saturn peripheral type...	0H (digital device)
Data size··········	2H (2 bytes)

●Explanation of each data

Right, Left, Down, Up...	When you press the key with the cross key, it becomes "0"
Start, ATRG, CTRG, BTRG・・・・・・	When you press the XTRG, YTRG, ZTRG button, it becomes "0"
RTRG,LTRG・・・・・・・・・・・・	The analog threshold returns digital data and becomes "0" when the button is pressed.

Note: Analog values are not output in this putt mode

The lower 3 bits (bits 2 to 0) of 2nd DATA are [111b], but please do not use them to maintain compatibility with other peripherals.

●Explanation of each data

◆Digital section

Right, Left, Down, Up・・・・・・・・・	When you press the key with the cross key, it becomes "0"
Start, ATRG, CTRG, BTRG・・・・・・ XTRG,YTRG,ZTRG	When the button is pressed, it becomes "0"
RTRG,LTRG・・・・・・・・・・・・	The analog threshold returns digital data and becomes 0 when the button is pressed.

◆Analog section

AX7〜AX0,AY7〜AY0・・・・・・・・・	Outputs the absolute value of the A/D converter output without sign. Notes
AL7〜AL0,AR7〜AR0・・・・・・・・・	Outputs the absolute value of the A/D converter output without sign

＜ Analog pad output data＞

●Notes

When the AX, AY keys are pressed all the way, the trajectory will be a concentric circle with a radius of 128 centered on AX, AY = (80H, 80H), so when pressed diagonally, the trajectory will be the maximum value (255) or the minimum value. Value (0) is not output. Also, each coordinate in the diagram indicates the main position, but the actual input value can indicate any position within the circumference.

＜ L/R button output data ＞

The lower 3 bits (bits 2 to 0) of 2nd DATA are [111b], but please do not use them to maintain compatibility with other peripherals.
