SFR:name
Returns 1 if the device has an ADV UART
Returns a 1 if the device has CCP number x
Returns a 1 if the device has TIMER
number x
Smallest number of bytes that can be
written to FLASH
Smallest number of bytes that can be
erased in FLASH
Returns the number of bytes at an address
location
Returns the size of an instruction in bits
Returns the number of RAM bytes available
for your device.
Returns the address of the specified special
file register. The output format can be used
with the preprocessor command #bit. name
must match SFR denomination of your
target PIC (example: STATUS, INTCON,
TXREG, RCREG, etc)
BIT:name
SFR_VALID:name
BIT_VALID:name
Returns the bit address of the specified
special file register bit. The output format
will be in “address:bit”, which can be used
with the preprocessor command #byte.
name must match SFR.bit denomination of
your target PIC (example: C, Z, GIE,
TMR0IF, etc)
Returns TRUE if the specified special file
register name is valid and exists for your
target PIC (example:
getenv("SFR_VALID:INTCON"))
Returns TRUE if the specified special file
register bit is valid and exists for your target
PIC (example:
getenv("BIT_VALID:TMR0IF"))
PIN:PB Returns 1 if PB is a valid I/O PIN (like A2)
UARTx_RX
UARTx_TX
SPIx_DI
Returns UARTxPin (like PINxC7)
Returns UARTxPin (like PINxC6)
Returns SPIxDI Pin
