Addition of workaround for a slowly decaying VDD ramp. 2.) Addition of Section 2.5 RST_E102 - VDD Monitor Disabled in the errata to explain why a slowly decaying VDD ramp can cause oscillations on the /RST pin and VDD monitor to become disabled. A workaround is suggested by having firmware enable the VDD monitor as the first instruction executed after a reset or in startup routine. This problem is fixed in revision F devices with date codes of 1532 and later.
