8.8.2.9
VDDH provides power for the 5-V I/O operations. It is a nominal 5.0 V.
8.8.2.10
IRAMSTBY is the data retention power supply for all on-board RAM arrays (CALRAM, DPTRAM,
DECRAM). It has a shunt regulator circuit of approximately 1.7 volts that diverts excess current to ground
in order to regulate voltage on the IRAMSTBY power supply pin. Run current is supplied by normal VDD.
IRAMSTBY must be connected to a positive power supply, via a register, and bypassed by a capacitor to
ground (see
