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 6DualPlus/6QuadPlus reference manual

(IMX6DQPRM). 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.
