Boost registers keep and reset control. Self reset
function: it can recover to 0 when set 1 :

0x37[5], 0x37[3:2] Boost relative bits. (default)
1 : Boost relative Reg recover to default value.
When HWEN OFF and BCTRL = 0 (default), Boost
keeps relative Reg.
When HWEN ON and BCTRL = 1, Boost recover to
default value. BCTRL become 0 automatically,
Boost relative Reg is kept.
When HWEN ON and BCTRL = 0, Boost relative
can be written normally.
