E' (excluding the DP bit)
There is no restriction other than by the DP bit.
(c) BANK 1/0
This bit can be rewritten freely even when the DP bit is 1.

(e) DP
DP
← 1: Rewriting is possible 62 s after the DP bit changes to 0.
DP
← 0: See "Temporarily canceling DP = 1 is a system for which DP is set at 1."
