Constructor Detail

TurboPicCore

Method Detail

createAndInitializeMemoryArrays

public void createAndInitializeMemoryArrays()

clearLabels

public void clearLabels()

setEnableWDT

public void setEnableWDT(boolean b)

setEnableIRQs

public void setEnableIRQs(boolean b)

isSpecialRegister

public boolean isSpecialRegister(int addr)

isNormalRegister

public boolean isNormalRegister(int addr)

setCodeBreakPoint

public void setCodeBreakPoint(int addr)

isCodeBreakPoint

public boolean isCodeBreakPoint(int addr)

readReg

public int readReg(int _addr7)

read the PIC file register selected by 7-bit parameter _addr7. This function uses the page bits (STATUS.RP1 and STATUS.RP0) to select the full 9-bit memory file address, and should behave like the PIC. For example, reading INDF will use indirect addressing, reading INDF(0) will return 0, and reading unimplemented addresses will return 0.

readRegRaw

public int readRegRaw(int _addr9)

read a register specified by its full PIC16XX family (9-bit) file address. This method is used for the GUI and debuggers, which may want to read *all* file addresses directly without using the STATUS register page mode bits. For example, calling readRegRaw( 0x86 ) will return the value of the TRISB register without consulting the page mode bits.

Reading INDF will still use the PIC indirect addressing method via FSR.

readPortA

public int readPortA()

read operation on PORT A.

readPortB

public int readPortB()

read operation on PORT B.

writePortA

public void writePortA(int value)

write operation to PORT A. This dummy implementation just writes to _PORTA_LATCH, without further I/O activity.

writePortB

public void writePortB(int value)

write operation to PORT B. This dummy implementation just writes to _PORTB_LATCH, without further I/O activity.

writeTrisA

public void writeTrisA(int value)

write operation on the TRIS A register. This writes the value to the _TRISA variable.

writeTrisB

public void writeTrisB(int value)

write operation on the TRIS B register.

writePCL

public void writePCL(int value)

write PCL pseudo register: this writes the lower 8 bits of the _PC program counter register, while the upper 5 bits are taken from _PCH.

writeReg

public void writeReg(int _addr7,
                     int value)
