Revision Description
â Battery voltage is not measured while in Hibernate mode.
â 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.
â 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.
â A note on Schmitt inputs was added to the GPIO chapter:
Pins configured as digital inputs are Schmitt-triggered.
â The Buffer type on the WAKE pin changed from OD to - in the Signal Tables.
â The "Differential Sampling Range" figures in the ADC chapter were clarified.
â The last revision of the data sheet (revision 2550) introduced two errors that have now been corrected:
â The LQFP pin diagrams and pin tables were missing the comparator positive and negative input
pins.
â The base address was listed incorrectly in the FMPRE0 and FMPPE0 register bit diagrams.
â Additional minor data sheet clarifications and corrections.
