(1)
Source currents (out of the device) are negative, while sink currents (into the device) are positive.
(2)
This does not apply to the PORRST pin. For PORRST exceptions, see the RST and PORRST Timings section.
(3)
These values help to determine the external RC network circuit. For more details, see the TMS470R1x System Module Reference Guide
(literature number SPNU189).
(4)
VOL and VOH are linear with respect to the amount of load current (IOL/IOH) applied.
(5)
Parameter does not apply to input-only or output-only pins.
(6)
The 2-mA buffers on this device are called zero-dominant buffers. If two of these buffers are shorted together and one is outputting a
low level and the other is outputting a high level, the resulting value is always low.
