• Bits[5:0]
If set to “1”, the corresponding bit (pin) IO[5:0] is configured as an output. Data may then
be written to that output by writing to the IO_DATA register. If set to “0”, the correspond-
ing bit (pin) may be either a button input (refer to the Button Detect Register, $34) used
to wake the part up or a normal digital input.
Table 19. I/O Pin Definition
• Bits[7:6]: Reserved
These bits read “0”.
• Bits[5.0]
If enabled in the IO_ENAB register and not in test mode, the data in Bits[5:0] goes to the
corresponding general-purpose output IO [5:0].
• Bits[7:6]: Reserved
This bit reads “0”.
• Bits[5:0]
These bits directly read the data from the I/O pins IO[5:0]. Writes to these bits have no
effect.
