Note:
  1. Conditions:
    • No peripheral modules are operating (i.e. all peripherals inactive)
    • MCLK all APB clock masked except MCLK and NVMCTRL
    • MCLK.AHBMASK = 0x00C00FFF
    • BOD33 is disabled unless noted
    • I/Os are inactive input mode with input trigger disabled
    • All clock generation sources disabled unless otherwise specified
    • WDT, CFD Clock Fail Detect disabled
    • RESET = VDD
  2. For the PIC32CX SG60/SG61 variants, the current consumption of the HSM is not taken into account and must be added according to its operating mode. Refer to the “PIC32CX SG60/SG61 Hardware Security Module Addendum (DS60001750)” for additional information.
