TABLE 6-3: RESET DELAY TIMES FOR VARIOUS DEVICE RESETS Reset Type Clock Source SYSRST Delay System Clock Delay Notes POR(6) EC TPOR + TPWRT + TRST — 1, 2, 7 FRC, FRCDIV TPOR + TPWRT + TRST TFRC 1, 2, 3, 7 LPRC TPOR + TPWRT + TRST TLPRC 1, 2, 3, 7 ECPLL TPOR + TPWRT + TRST TLOCK 1, 2, 4, 7 FRCPLL TPOR + TPWRT + TRST TFRC + TLOCK 1, 2, 3, 4, 7 XT, HS, SOSC TPOR + TPWRT + TRST TOST 1, 2, 5, 7 XTPLL, HSPLL TPOR + TPWRT + TRST TOST + TLOCK 1, 2, 4, 5, 7 BOR EC TPWRT + TRST — 2, 7 FRC, FRCDIV TPWRT + TRST TFRC 2, 3, 7 LPRC TPWRT + TRST TLPRC 2, 3, 7 ECPLL TPWRT + TRST TLOCK 2, 4, 7 FRCPLL TPWRT + TRST TFRC + TLOCK 2, 3, 4, 7 XT, HS, SOSC TPWRT + TRST TOST 2, 5, 7 XTPLL, HSPLL TPWRT + TRST TFRC + TLOCK 2, 3, 4, 7 All Others Any Clock TRST — 7 Note 1: TPOR = Power-on Reset delay. 2: TPWRT = 64 ms nominal if regulator is disabled (ENVREG tied to VSS). 3: TFRC and TLPRC = RC Oscillator start-up times. 4: TLOCK = PLL lock time. 5: TOST = Oscillator Start-up Timer (OST). A 10-bit counter waits 1024 oscillator periods before releasing the oscillator clock to the system. 6: If Two-Speed Start-up is enabled, regardless of the Primary Oscillator selected, the device starts with FRC, and in such cases, FRC start-up time is valid. 7: TRST = Internal State Reset Timer Note: For detailed operating frequency and timing specifications, see Section 28.0 “Electrical Characteristics”. |
