Register B5h: Min Temp Adjust Temp and Delay AMB (Zone 2)
This register becomes read only when the Lock bit is set. Any further attempts to write to this register
shall have no effect.
Bits[5:4] Min Temp Adjust for Ambient Temp Sensor (Zone 2)
See
Min Temp Adjust bits.
Bits[1:0] Min Temp Adjust Delay for Ambient Temp Sensor (Zone 2)

definition of the Min Temp Delay bits.
Register B6h: Min Temp Adjust Delay RD1, RD2 (ZONE 1 & 3) Register
This register becomes read only when the Lock bit is set. Any further attempts to write to this register
shall have no effect.
Bits[7:4] are the bits to program the time delay for subsequently adjusting the low temperature limit
value for zones 1&3 once an adjustment is made. These bits are defined as follows: RxAD[1:0]:
