Voltage Limit
Setting the Configuration Register 1 lock bit has no effect on these registers.
Rev. 0 | Page 40 of 48
High limits: An interrupt is generated when a value exceeds its high limit (> comparison).
Low limits: An interrupt is generated when a value is equal to or below its low limit (≤ comparison).

Temperature Limit
Setting the Configuration Register 1 lock bit has no effect on these registers. When the temperature readings are in offset binary format,
an offset of 64 degrees (0x40 or 0100000) must be added to all temperature and THERM limits. For example, if the limit is 50°C the
actual programmed limit is 114.

This is an 8-bit limit with a resolution of 22.76 ms allowing PROCHOT assertion limits of 45.52 ms to 5.82 seconds to be programmed. If
the PROCHOT assertion time exceeds this limit, Bit 1 of Interrupt Status Register 2 (0x11) is set. If the limit value is 0x00, an interrupt is
generated immediately upon assertion of the THERM input.
