Variable Documentation

unsigned char rom_port1_ddr

ROM shadow of port 1 DDR.

unsigned char rom_port2_ddr

ROM shadow of port 2 DDR.

unsigned char rom_port3_ddr

ROM shadow of port 3 DDR.

unsigned char rom_port4_ddr

ROM shadow of port 4 DDR.

unsigned char rom_port5_ddr

ROM shadow of port 5 DDR.

unsigned char rom_port6_ddr

ROM shadow of port 6 DDR. Port 6 is connected to both LCD and active sensor output. As lcd_refresh() is a ROM call, we need to update this location if active sensors are to remain active after a LCD refresh. Referenced by i2c_read_ack(), and lcd_init().

unsigned char rom_port7_pin

ROM shadow of port 7 pin.
