Descriptions
Page Erase/Program Protection Status Bits (n = 0 ~ 127)
PPSB[n] = OB_PP[n]
0: The corresponding page n is protected
1: The corresponding page n is not protected
The content of this register is not dynamically updated and will only be reloaded
from the Option Byte when any kind of reset occurs. The erase or program function
of the specific page is not allowed when the corresponding bits of the PPSR
registers are reset. The reset value of PPSR [127:0] is determined by the Option
Byte OB_PP [127:0] bits. Each page erase/program protection status bit protects
one page. The other remained bits of the OB_PP field and PPSR registers are
reserved.
