For Infineon XC164KM-8F — Port 5 (14-bit Input with Disable)
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 an 16-bit input-only port.
Data written to this port is not output on the device pins.
P5 represents the P5 SFR. The HEX value and value of
each bit is displayed and may be changed from this dialog.
P5DIDIS represents the P5DIDIS SFR which is used to
disconnect the P5 SFR bits from the respective Port 5 pin. When
P5DIDIS.x=0, P5.x is connected to the Port 5.x pin. When
P5DIDIS.x=1, P5.x is disconnected from the Port 5.x pin.
Pins represents the states of the pins on the simulated
MCU. You may set the level of the input pin to high (1) or low (0).
The corresponding value will be set in the respective P5 bit.
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 */
