Deep Sleep Power Down (ZZ)
ZZ controls the sleep mode operation. Enabling sleep mode causes all other inputs to be do not cares. ZZ
places all die into internal low power even while system power is still applied to VDD. Pin 12 on the
UT8MR8M8 are routed to a three pin header J2. The center pin on the three pin J2 header is tied to the ZZ
pin, the other pins are tied to VDD and VSS. Please refer to the UT8MR8M8 datasheet for further
information.
