This bit is unused and always read as 1.
When this bit is a 0, a Local High Alarm event will generate an ALERT.
When this bit is a 1, a Local High Alarm will not generate an ALERT

Sets the conversion rate of the LM63.
00000000 = 0.0625 Hz
00000001 = 0.125 Hz
00000010 = 0.25 Hz
00000011 = 0.5 Hz
00000100 = 1 Hz
00000101 = 2 Hz
00000110 = 4 Hz
00000111 = 8 Hz
00001000 = 16 Hz
00001001 = 32 Hz
All other values = 32 Hz
With the LM63 in the STANDBY mode a single write to this register will
initiate one complete temperature conversion cycle.
