5.13 Internal Pullup and Pulldown Characteristics

INTERNAL PULLUP AND PULLDOWN RESISTOR CHARACTERISTICS(1)CONDITIONSMINMAXUNIT
Weak pullup resistance - FLSH_CSZVDD_FLSH = 3.3V4259kΩ
Weak pullup resistance - SSP0_CSZ_0VDD_INTF = 3.3V1826kΩ
Weak pullup resistance - JTAGTRSTZ, JTAGTDI, JTAGTMS1, JTAGTMS2, VDD18 = 1.8V3184kΩ
Weak pulldown resistance - JTAGTCK, HWTEST_EN, TSTPT_0, TSTPT_1, TSTPT_2, TSTPT_3, TSTPT_4, TSTPT_5, TSTPT_6, TSTPT_7, GPTP0, GPTP1, GPTP2VDD18 = 1.8V3171kΩ
(1) An external 5.7kΩ or less pullup or pulldown resistor (if needed) is sufficient for any voltage condition to correctly override any associated internal pullup or pulldown resistance.
