Digital I/O Ports
The C515 allows for digital I/O on 48 lines grouped into 6 bidirectional 8-bit ports. Each port bit
consists of a latch, an output driver and an input buffer. Read and write accesses to the I/O ports P0
through P5 are performed via their corresponding special function registers P0 to P5.
The output drivers of port 0 and 2 and the input buffers of port 0 are also used for accessing external
memory. In this application, port 0 outputs the low byte of the external memory address, time-
multiplexed with the byte being written or read. Port 2 outputs the high byte of the external memory
address when the address is 16 bits wide. Otherwise, the port 2 pins continue emitting the P2 SFR
contents.
Analog Input Ports
Ports 6 is available as input port only and provides two functions. When used as digital inputs, the
corresponding SFR P6 contains the digital value applied to the port 6 lines. When used for analog
inputs the desired analog channel is selected by a three-bit field in SFR ADCON. Of course, it
makes no sense to output a value to these input-only ports by writing to the SFR P6. This will have
no effect.
lf a digital value is to be read, the voltage levels are to be held within the input voltage specifications
(
V
IL
/
V
IH
). Since P6 is not bit-addressable, all input lines of P6 are read at the same time by byte
instructions.
Nevertheless, it is possible to use port 6 simultaneously for analog and digital input. However, care
must be taken that all bits of P6 that have an undetermined value caused by their analog function
are masked.
