For Infineon XC2288I-136F — Port 5 (16-bit Input)
Simulation support for this peripheral or feature is comprised of:
- Dialog boxes which display and allow you to change peripheral configuration.
- VTREGs (Virtual Target Registers) which support I/O with the peripheral.
These simulation capabilities are described below.
Parallel Port 5 Dialog
This dialog displays the SFR and pins of Port 5. This port has
alternate functions but it may be used as a 16-bit input-only port.
Data written to this port is not output on the device pins.
P5 / Pins represents the P5 SFR which is a direct
reflection of the pins. The checkboxes represent the states of the
pins on the simulated MCU. You may set the level of the input pin
to high (1) or low (0).
Data Type: unsigned int
The PORTx VTREGs represent the I/O pins of the simulated
MCU for Port 0, Port 1, and so on. You may read PORTx to
determine the state of the output pins of that port. For example, in
the command window, you may type,
to obtain the value corresponding to the set pins of Port 8. You
may also change the input values of port pins by changing the value
of the VTREG. For example,
sets bits 4-7 and clears bits 0-3 and 8-15. You may use the
bitwise operators AND(&), OR(|) and XOR(^) to change individual
bits of the PORTx VTREGs. For example:
PORT2 |= 0x0001; /* Set P2.0 Pin */
PORT8 &= ~0x0002; /* Clr P8.1 Pin */
PORT7 ^= 0x0080; /* Toggle P7.7 Pin */
