21.How can SW2 be used for PMIC wake up?
SW2 is connected to the PMIC_Wakeup_In pin (P0.4) of PSoC 6 MCU. A logic high input at the
PMIC_Wakeup_In pin can wake up the system and enable the PMIC. See the Backup chapter in
PSoC 6 MCU Architecture Technical Reference Manual
for more details of this feature.
SW2 should be externally pulled down to ground to use PMIC control. Moreover, when the switch
is pressed, the active HIGH logic should push P0.4 to the VBACKUP supply. However, the kit is
configured by default to use active LOW logic as described in
. In
addition, in Rev04 version of the kit, the active HIGH logic for SW2 pushes P0.4 to VBACKUP.
Therefore, the following re-works on the kit are required to use the PMIC control feature:
■
Remove R65 and populate the 0Ω R66.
■
Remove R67 and populate a 10KΩ resistor at R68.
