Date: Wed, 18 Nov 2015 18:04:08 +0800	[thread overview]
Message-ID: <1447841049-5010-2-git-send-email-wenyou.yang@atmel.com> (raw)
In-Reply-To: <1447841049-5010-1-git-send-email-wenyou.yang@atmel.com>

Increase the delay time until the value written to INIT can be
read back to ensure that the previous value written to INIT has
been accepted.
