DDRC[5:0] — Data Direction Register C Bits
Figure 22-10
When bit DDRCx is a logic 1, reading address $0002 reads the PTCx data latch. When bit DDRCx is a
logic 0, reading address $0002 reads the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
Freescale Semiconductor
These read/write bits control port C data direction. Reset clears DDRC[7:0], configuring all port C pins
as inputs.
1 = Corresponding port C pin configured as output
0 = Corresponding port C pin configured as input
X = don’t care
Hi-Z = high impedance
1. Writing affects data register, but does not affect input.
shows the port C I/O logic.
Value
Avoid glitches on port C pins by writing to the port C data register before
changing data direction register C bits from 0 to 1.
