@CHIP-RTOS C Library V2.00 - Hardware API
hal_write_pios
Write to the programmable I/O pins. Before the value is written,
the value is combined with the wAND and wXOR parameters as:
PIO[0..13] = (data & wAND) ^ wXOR
To write value to the programmable I/O pins without change,
set wAND=0xFFFF and wXOR=0x0000.
Only PIO pins that are defined as outputs can be written. void hal_write_pios ( unsigned short value,
unsigned short wAND,
unsigned short wXOR ); Parameters
value
- output data
wAND
- mask
wXOR
- bit inverter
Return Value
- -- none --.
Comments
- & = bit wise AND
^ = bit wise XOR
