1: Port C pin with pull-up
Port C Option Register (PORT_C_OR)
Configuration Register 33 (021h) Read/Write
Reset Value: 0000 0000 (00h)
Note:
This register is not used in 16/20 pin devices
Bit 7-6: Not Used
Bit 5-0:
ORC5-0
Port C option (see Table 7.1)
Port C Data Direction Register (PORT_C_DDR)
Configuration Register 34 (022h) Read/Write
Reset Value: 0000 0000 (00h)
Note:
This register is not used in 16/20 pin devices
Bit 7-6: Not Used
Bit 5-0:
DDRC5-0
Port C direction (see Table 7.1)
0: Port C pin configured as input
1: Port C pin configured as output
Note:
in order to achieve low current consuption,
the port pins must be configured as input pull-up,
even though they are not existing in the package.
For example in 20 pin devices, the pins PB6-7 and
PC0-7 must be configured in input pull-up.
