Flash non-volatile write protection I register high (FNVWPIRH)
FNVWPIRH (0x0E DFB6)
Table 21.
Flash non-volatile write protection I register low Mirror (FNVWPIRL-m)
FNVWPIRL-m (0x0E DFB0)
This register is mirroring the register at FVWPIRL (address 0x0E DFB4). It is intended to
maintain software compatibility with the ST10F273E.
In applications ported from a ST10F273E, FVWPIRL-m register (address 0x0E DFB0) must
be used to maintain the existing Flash drivers.
In applications ported from a ST10F272x, FVWPIRL register (address 0x0E DFB4) must be
used to maintain existing drivers.
Flash non-volatile write protection I register high Mirror (FVWPIRH-m)
FVWPIRH-m (0x0E DFB2
This register is mirroring the register at FVWPIRH (address 0x0E DFB6). It is intended to
maintain software compatibility with the ST10F273E.
In applications ported from a ST10F273E, FVWPIRH-m register (address 0x0E DFB2) must
be used to maintain the existing Flash drivers.
In applications ported from a ST10F272x, FVWPIRH register (address 0x0E DFB6) must be
used to maintain existing drivers.
