Peripheral Simulation

For Toshiba TMPM330FYFG — I/O Ports A-K (78 bits)

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.

PORTx VTREG
Data Type: unsigned long

The PORTx VTREGs represent the I/O pins of the simulated MCU for Port A, Port B, and so on. PORTA represents Port A, PORTB represents Port B, etc. You may read PORTx to determine the state of the output pins of that port. For example, in the command window, you may type,

PORTA

to obtain value corresponding to the set pins of Port A. You may also change the input values of port pins by changing the value of the VTREG. For example,

PORTA=0xF0

sets the upper four port pins of Port 1 to a value of 1 and the lower 4 port pins to a value of 0. You may use the bitwise operators AND(&), OR(|) and XOR(^) to change individual bits of the PORTx VTREGs. For example:

PORTB |=  0x01;  /* Set P1.0 Pin */
PORTD &= ~0x02;  /* Clr P3.1 Pin */
PORTB ^=  0x80;  /* Toggle P1.7 Pin */
