STATUS BIT
(1): Bit BATFAIL cannot be set by SPI. BATFAIL is set when V
(2): Watchdog ON or OFF depends on the RCR register bit D3.
(3): Before entering sleep mode, bit NOSTOP in RCR register must be previously set to 1.
(4): Stop command should be replaced by Stop Watchdog OFF. MCTR2=0, MCTR1= MCTR0=1
