OMAP5912 Wake-up Capabilities
Table 10. Event Captures for Peripheral Wake-up Capability (Continued)
Peripheral Event Capture
Emulation wake up The emulation is also able to wake up the
ARM926EJS. This wake up event is also
merged with the application wake up
event.
USB_OTG Asynchronous detection on USB device
controller to request the USB clock
MPUIO Can wake up the system by sampling
data at low frequency and sending
interrupt to MCU
Notes: 1) When the wake-up is done through the GPIO, the programmer must ensure that the GPIO direction is set up as
input.
2) Depending on the OMAP5912 configuration before entering into power-down mode, the GPIO can wake either
the entire system or only a specific subsystem.
3) In addition to the wake-up capability mentioned in the above table, several peripherals are also able to generate
their own wake-up request. These requests are merged and sent to OMAP3.2 and the MPU level 2 interrupt
handler as a global wake-up request.
3.1 OMAP5912 Pin Description
54 Introduction
See Chapter 22, Pinout, for I/O pin description. It includes the pin description
(location on the ballout, reset state, buffer used, signal description, electrical
information, and buffer description).
The OMAP5912 boot configuration pins can select either:
-
Boot from internal boot ROM or from external memory
-
The configuration of the external memory (either address/data
multiplexed or separate address and data)
