NOTE

WDOG1_B output signals (for each one of the Watchdog modules) do not

have dedicated pins, but are muxed out through the IOMUX. See the

IOMUXC chapter of the i.MX 6Solo/6DualLite Reference Manual

(IMX6SDLRM).

4.9.3

External Interface Module (EIM)

The following subsections provide information on the EIM. Maximum operating frequency for EIM data

transfer is 104 MHz. Two system clocks are used with the EIM:

•

ACLK_EIM_SLOW_CLK_ROOT is used to clock the EIM module.

The maximum frequency for CLK_EIM_SLOW_CLK_ROOT is 132 MHz.

•

ACLK_EXSC is also used when the EIM is in synchronous mode.

The maximum frequency for ACLK_EXSC is 104 MHz.

Timing parameters in this section that are given as a function of register settings.

4.9.3.1

EIM Interface Pads Allocation

EIM supports 32-bit, 16-bit and 8-bit devices operating in address/data separate or multiplexed modes.

Table 41 provides EIM interface pads allocation in different modes.
