NOTE:
Only gpio_1, gpio_9, gpio_30, and gpio_31 can be used to generate a direct wake-up event.
The other GPIO1 pins cannot be used to generate a direct wake-up event, because they are
connected to the device I/O pad logic in the CORE power domain (VDD2). When the CORE
power domain is OFF, the VDD2-supplied I/O pins of GPIO1 cannot generate a wake-up
event.
A.18 Initialization
A.18.1 Overview
The OMAP36xx in CYN package devices use the same ROM code version as the OMAP36xx high-tier
device. The ROM code function is the same as is all embedded data in the ROM code itself. The following
data are hardcoded in the ROM code and hold OMAP3630 meaning:
•
ASIC ID identificator (equal to 0x3630)
•
TI default value for USB device descriptor field product ID (equal to 0xD00E)
•
TI default value for product ID string descriptor (equal to OMAP3630)
A.18.2 Preinitialization
A.18.2.1 Power Connections
describes the power supply pins for the OMAP36xx in CYN package devices. The pins
highlighted in orange are not available on the OMAP36xx in CYN package.
