Options (OPTR)
Mask option register (MOR)
(1) This bit is set each time there is a power-on reset.
(2) The state of the WDOG bit after reset is dependent upon the mask option selected; 1=watchdog enabled, 0=watchdog disabled.
(3) This register is implemented in EEPROM; therefore reset has no effect on the individual bits.
(4) This register is implemented in EPROM; therefore reset has no effect on the individual bits.
