There are 2 syscon pins dedicated to detect the disc insertion. One of pins powers a IR-LED (emitter), and the other pin is connected to a photo-transistor (receiver), both aligned with each other<br>

When the disc interrupts the light beam a control signal is sent to syscon in the receiver pin. See [[BL1-001]] and [[BL2-001]]

*RSX_RESET (syscon output, RSX input) <--------- Connected to [[RSX]] pad AW5 ([[Template:RSX pad layout 41x41|RSX layout 41x41]]). Exists in [[Template:Syscon_pinout_LQFP_100_pins]]
*POW_FAIL (syscon input, unknown source)
*RSX_VINTE1 / VD_VINT1 (syscon input, RSX output) <--------- Connected to [[RSX]] pad AL38 ([[Template:RSX pad layout 41x41|RSX layout 41x41]]). Exists in [[Template:Syscon_pinout_LQFP_100_pins]]
*SB_RESET (syscon output, to south bridge)
*<strike>RSX_CGRST (syscon output, RSX input) <--------- Connected to [[RSX]] pad AV6 ([[Template:RSX pad layout 41x41|RSX layout 41x41]])</strike> Nerfed in RSX with a 10k resistor to GND
*SB_CGAST (syscon output, to south bridge)
*SB_RESET (syscon output, south bridge input)
*RSX_RESET (syscon output, to RSX)
*<strike>SB_CGRST (syscon output, south bridge input)</strike> <--- Nerfed too, like the RSX_CGRST ?
*RSX_CGAST (syscon output, to RSX)
*BE_RESET (syscon output, CELL input)
*RSX_FBVDD_SEL (syscon output, to RSX)
*BE_POWGOOD (syscon output, CELL input)
*VD_VINT0 (syscon input, from RSX)
*DISC_PHOT_LED (syscon output, bluray input) <--- disc insertion IR (emitter)
*VD_VINT1 (syscon input, from RSX)
*DISC_IN (syscon input, bluray output) <--- disc insertion phototransistor (receiver)
*SW_HDD (syscon output, to HDD)
*DISC_IN_MECHA (syscon output)
*EJECT_MECHA (syscon output)
*RSX_FBVDD_SEL (syscon output, RSX input) <----- existence doubtful
*SW_ATA (syscon output, HDD power switch input)
*POW_FAIL (syscon input, unknown source) <--- is the same than ACIN_DET pin 41 ?
*MK_EN (syscon output, MK input) <--- connected to Texas Instruments-SCEI Clock Generator CDC972 '''through a 47ohm resistor''' ?
*XCG_EN (syscon output, MK/secondary inputs) <--- connected to the clock generator/s
*I2CBUS_EN (syscon output, I2C switch input) <------ connected to 2 pins of the chip dedicated to "duplicate" the MK_I2C_SCL/MK_I2C_SDA bus into a secondary bus: XCG_I2C_SCL/XCG_I2C_SDA
*HDMI_INT (syscon input, HDMI output) <--- probably there is an intermediate component in between HDMI and syscon similar to [[TC7WP3125FK ]]
*HDMI_RST0 (syscon output, HDMI input)
*DVE_RST (syscon output, HDMI input)
*WLAN_RESET (syscon output)
*AUDIO_MUTE (syscon output). <abbr title="and diode ?">Transistor</abbr> ---> to 2 transistors ---> to 2 pins of the (unknown) audio chip (stereo audio output left/right), and to pins 9 and 11 of the MultiAV connector [[Template:Syscon_pinout_BGA_200_pads|See]]
 
== Connections with the BD motor driver ? ==
I been wondering if syscon have some connection/s to switch the power line/s of [[Bluray Drive#Drivers]] - [[BD7761EFV]] or [[BD7763EFV]] --[[User:Sandungas|Sandungas]] ([[User talk:Sandungas|talk]]) 16:35, 30 September 2022 (UTC)
