The Θ
Characteristics chapter.
Bit 31 of the DC3 register was incorrectly described in prior versions of the datasheet. A reset of 1
indicates that an even CCP pin is present and can be used as a 32-KHz input clock.
Values for I
Characteristics" chapter.
The "Hibernation Module DC Electricals" table was added to the "Electrical Characteristics" chapter.
The T
was changed from a max of 100 to 250.
The maximum value on Core supply voltage (V
Characteristics" chapter was changed from 4 to 3.
The operational frequency of the internal 30-kHz oscillator clock source is 30 kHz ± 50% (prior datasheets
incorrectly noted it as 30 kHz ± 30%).
A value of 0x3 in bits 5:4 of the MISC register (OSCSRC) indicates the 30-KHz internal oscillator is the
input source for the oscillator. Prior datasheets incorrectly noted 0x3 as a reserved value.
The reset for bits 6:4 of the RCC2 register (OSCSRC2) is 0x1 (IOSC). Prior datasheets incorrectly noted
the reset was 0x0 (MOSC).
Two figures on clock source were added to the "Hibernation Module":
–
–
The following notes on battery management were added to the "Hibernation Module" chapter:
–
–
A note on high-current applications was added to the GPIO chapter:
For special high-current applications, the GPIO output buffers may be used with the following restrictions.
With the GPIO pins configured as 8-mA output drivers, a total of four GPIO outputs may be used to sink
current loads up to 18 mA each. At 18-mA sink current loading, the VOL value is specified as 1.2 V.
The high-current GPIO package pins must be selected such that there are only a maximum of two per
side of the physical package or BGA pin group with the total number of high-current GPIO outputs not
exceeding four for the entire package.
A note on Schmitt inputs was added to the GPIO chapter:
Pins configured as digital inputs are Schmitt-triggered.
The Buffer type on the WAKE pin changed from OD to - in the Signal Tables.
The "Differential Sampling Range" figures in the ADC chapter were clarified.
Clock Source Using Crystal
Clock Source Using Dedicated Oscillator
Battery voltage is not measured while in Hibernate mode.
System level factors may affect the accuracy of the low battery detect circuit. The designer should
consider battery type, discharge characteristics, and a test load during battery voltage measurements.
