System idle
[1] '''24MHz active oscillator power consumption is included'''. As the board under test is equipped with iMX6UL revision 1.0, active oscillator is required to implement the fix described by errata ERR009455. Typical consumption of this oscillator is about 20mW. Future revision of the board will be populated with silicon revision 1.1 or newer. Thus active oscillator will be removed. For more details please refer to ''Chip Errata for the i.MX 6UltraLite''<ref name="IMX6ULCE">Freescale Semiconductor, ''Chip Errata for the i.MX 6UltraLite'', Rev. 0.1, 02/2016</ref>.
===System Optimized idle===In this case the <code>powersave</code> governor is used. As Most importantly, Ethernet interface is disabled, as described in ''i.MX 6UltraLite Power Consumption Measurement'' application note<ref name="AN5170">NXP Semiconductors, ''i.MX 6UltraLite Power Consumption Measurement'', Rev. 1, 04/2016</ref>, the use of this governor . This allows to reduce power consumption significantly in idle condition, because*processor's peripheral bus can be disabled as detailed well*external PHY is put in the following tablepower-down mode
