@CHIP-RTOS C Library - Hardware API


hal_write_bus

Write single byte to data bus.   The provided parameters are combined as follows to form the output byte value:

        output value = (data & wAND) ^ wXOR

To write the value to the address without modification, set wAND=0xFFFF and wXOR=0x0000.

For SC1x:

    void hal_write_bus ( unsigned short adr, unsigned char value,
                         unsigned short wAND,unsigned short wXOR );
For SC1x3:
    void hal_write_bus ( unsigned short adr, unsigned short value,
                         unsigned short wAND,unsigned short wXOR );

This function is deprecated! Use outport or outportb function from dos.h instead!

Parameters

adr

I/O Address

value

Value to be output

wAND

Mask applied to output

wXOR

Output bit inverter

Return Value

-- none --.

Comments

& = bit wise AND
^ = bit wise XOR
