All the switching regulators and linear regulators signals have been connected to J15,
J16, and J17, so they can be loaded and tested from there. They also have their
respective test points on the board. Switching regulators have a cut trace that allows the
output to be connected to the feedback signal on the board, i.e. SH6, SH9, SH10, SH11,
SH12, and SH16, which are shorted by default. The feedback signals are also available
on the load connectors (J15, J16, and J17), so the feedback point can be connected
directly to the load by opening the former cut traces and shortening SH67, SH68, SH69,
SH70, SH71, and SH72, respectively. VUSB2 and VGEN2 LDOs can be used with
either internal or external pass devices by configuring J9-J53 and J20-J66 jumpers,
respectively.
The MC34708 can be configured to be controlled by I
mode, J64 ties the CS pin to VCOREDIG, and J63 is intended to set the A0 address at
the MOSI pin. The following pins are connected to the KITUSBCOMDGLEVME, so they
can be controlled / monitored through the GUI: CS, CLK, MISO/SDA, MOSI, WDI, INT,
RESETB, RESETBMCU, STANDBY, GLBRST, SDWNB, and PWRON1.
The SPIVCC pin can be supplied from the SW4A:
The Power Up mode supply pins can be configured through the J57, J58, J59, J60, and
J61 pin headers on the board. The GPIOs pins are accessible through test points
labeled as GPIOLVx. The green D7 and D8 LEDs are provided on the board to verify the
performance of the PWM pins, or if desired, at the test points labeled as PWMx.
The BAT1 coin cell offers the possibility to keep the RTC running and save the contents
of some registers, even if the device is in the Off mode.
When an accessory is attached at either the Mini-B USB connector at J23, or the USB
type A connector at J25, the PMIC enters in the active mode of the accessory
identification process. The ID detection circuit determines what ID resistor is attached,
and the power supply type identification circuit determines what type of power supply is
connected. An Audio Type 1 or TTY accessory could be manually connected to the 4-pin
J68 header along with the USB OTG transceiver ID (UID) test point, which can also be
