• PWRGD_FPD_M2C: PWRGD_FPD_M2C is an acve-High output signal from the SOM power
system that indicates the power status of all SOM PS full-power domain (FPD) rails.
PWRGD_FPD_M2C is pulled High to 1.80V on the SOM. A carrier card can use this signal to
monitor FPD status.
Note: The K26 SOM does not have split rails for LPD and FPD. PWRGD_LPD_M2C and
PWRGD_FPD_M2C are ed together on the SOM.
• PWRGD_PL_M2C: PWRGD_PL_M2C is an acve-High output signal from the SOM power
system that indicates the power status of all SOM PL power rails. PWRGD_PL_M2C is pulled
High to 1.80V on the SOM. A carrier card can use this signal to monitor PL power status.
• VCCOEN_PS_M2C: VCCOEN_PS_M2C is an acve-High output signal from the SOM power
system to enable the PS V
CCO
rails that are supplied by the carrier card. A carrier card can use
this signal as an indicaon to turn power on for all PS peripherals.
• VCCOEN_PL_M2C: VCCOEN_PL_M2C is an acve-High output signal from the SOM power
system to enable the PL V
CCO
rails that are supplied by the carrier card. A carrier card can use
this signal as an indicaon to turn power on for all PL peripherals.
