SNLS579A April 2018 – November 2018 DP83TC811S-Q1
Overtemperature and undervoltage monitoring are always active in the DP83TC811S-Q1 by default. If an overtemperature condition, an undervoltage condition, or both conditions are detected, interrupt status flags are set in the INT_STAT2 Register 0x0013 – Interrupt Status Register #2. Additionally, temperature and voltage monitoring cycle period can be adjusted using the MON_CFG1 Register 0x0480 – Monitor Configuration Register #1 bits[2:0]. By default, sample time is set to 31 ms, but also has a configurable range of 16 ms to 240 ms. Single-run temperature and voltage monitoring is also supported when bit is set to 0b0 in the MON_CFG2 Register 0x0481 – Monitor Configuration Register #2, disabling period monitoring. To activate a single run, bit in MON_CFG2 register must be set after disabling period monitoring. Temperature monitor results are available in the MON_STAT1 Register 0x0483 – Monitor Status Register #1. VDDA and VDDIO supply monitor results are available in the MON_STAT2 Register 0x0484 – Monitor Status Register #2.
