3.1 Special Signal Considerations
The package contact assignments can be found in Section 6, “Package Information and Contact
Assignments.” Signal descriptions are defined in the i.MX 6Dual/6Quad reference manual (IMX6DQRM).
Special signal consideration information is contained in the Hardware Development Guide for i.MX
6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors (IMX6DQ6SDLHDG).
3.2 Recommended Connections for Unused Analog Interfaces
The recommended connections for unused analog interfaces can be found in the section, “Unused analog
interfaces,” of the Hardware Development Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of
Applications Processors (IMX6DQ6SDLHDG).
WDOG-2
(TZ)
Watchdog
(TrustZone)
Timer
Peripherals
The TrustZone Watchdog (TZ WDOG) timer module protects against
TrustZone starvation by providing a method of escaping normal mode and
forcing a switch to the TZ mode. TZ starvation is a situation where the
normal OS prevents switching to the TZ mode. Such a situation is
undesirable as it can compromise the system’s security. Once the TZ
WDOG module is activated, it must be serviced by TZ software on a
periodic basis. If servicing does not take place, the timer times out. Upon
a time-out, the TZ WDOG asserts a TZ mapped interrupt that forces
switching to the TZ mode. If it is still not served, the TZ WDOG asserts a
security violation signal to the CSU. The TZ WDOG module cannot be
programmed or deactivated by a normal mode Software.
EIM NOR-Flash /PSRAM
interface
Connectivity
Peripherals
The EIM NOR-FLASH / PSRAM provides:
• Support 16-bit (in muxed IO mode only) PSRAM memories (sync and
async operating modes), at slow frequency
• Support 16-bit (in muxed IO mode only) NOR-Flash memories, at slow
frequency
• Multiple chip selects
XTALOSC Crystal Oscillator
interface
— The XTALOSC module enables connectivity to external crystal oscillator
device. In a typical application use-case, it is used for 24 MHz oscillator.
