3.1.3Dedicated Output Port G

Port G is a 16-bit wide output-only port. The output drivers have a Totem-Pole configuration. The data driven by the output pin can be controlled by setting or clearing the appropriate bit in the G port Data register, address 0x2C. This is done using the OUT instruction, with the 0x2C address as an argument. Af- ter RESET low, the default settings for the G port outputs are 0 (logical low).

	Totem-Pole Output Port G
Data register address	0x2Ch
Possible input data values	N/A
Possible output data values	0 = Low 1 = High
Value after RESET low	0 = Low

The following table shows the bit locations of the port G address mapping:
