49 / 161 page ![]() Electrical Characteristics i.MX 6Solo/6DualLite Applications Processors for Industrial Products, Rev. 9, 11/2018 NXP Semiconductors 49 4.9.1 Reset Timings Parameters Figure 9 shows the reset timing and Table 35 lists the timing parameters. Figure 9. Reset Timing Diagram 4.9.2 WDOG Reset Timing Parameters Figure 10 shows the WDOG reset timing and Table 36 lists the timing parameters. Figure 10. WDOG1_B Timing Diagram NOTE XTALOSC_RTC_XTALI is approximately 32 kHz. XTALOSC_RTC_XTALI cycle is one period or approximately 30 μs. 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. Table 35.
