119 / 244 page  Figure 7-9. MCU_RESETz, MCU_RESETSTATz, and RESETSTATz Timing Requirements and Switching Characteristics Table 7-9. RESET_REQz Timing Requirements see Figure 7-10 NO. PARAMETER MIN MAX UNIT RST15 tw(RESET_REQzL) (1) Pulse Width minimum, RESET_REQz active (low) 1200 ns (1) This timing parameter is valid only after all supplies are valid and MCU_PORz has been asserted for the specified time. Table 7-10. RESETSTATz Switching Characteristics see Figure 7-10 NO. PARAMETER MIN MAX UNIT RST16 td(RESET_REQzL-RESETSTATzL) Delay time, RESET_REQz active (low) to RESETSTATz active (low) T(1) ns RST17 td(RESET_REQzH-RESETSTATzH) Delay time, RESET_REQz inactive (high) to RESETSTATz inactive (high) W(2) ns (1) T = Reset Isolation Time (Software Dependent) (2) W = Max [300 μs (Typical) from RESETz_REQz inactive (high), Reset Isolation Time + 300 μs (TYP) from RESET_REQz active (low)] Figure 7-10.
