Purpose Write to an 8, 16 or 32-Bit Output Port

Used by n Task n ISP n Timer Procedure n Restart Procedure n Exit Procedure

Setup Prototype in file

CJZZZTF.H or macro in file

CJZZZCC.H.

#include "CJZZZ.H"

void CJ_CCPP cjcfout8(void *port, CJ_T32 data);

void CJ_CCPP cjcfout16(void *port, CJ_T32 data);

void CJ_CCPP cjcfout32(void *port, CJ_T32 data);

Description port is the address of an 8, 16 or 32-bit memory-mapped device output

port.

data is the 8, 16 or 32-bit value to be output to the port.

Interrupts o Disabled o Enabled o Restored

Returns Nothing

Cjcfout8 outputs the least significant 8 bits of data to the port.

Cjcfout16 outputs the least significant 16 bits of data to the port.

Cjcfout32 outputs the full 32 bits of data to the port.

Example #include "CJZZZ.H"

/* Console status register */

#define CONSTAT ((CJ_T8 *)0xFFFA002DL)

/* Console data register */

#define CONDATA ((CJ_T8 *)0xFFFA002FL)

void CJ_CCPP conout(char ch) {

/* Wait for ready */

while ( (cjcfin8(CONSTAT) & 0x80) == 0 )

;

/* Write character */

cjcfout8(CONDATA, (CJ_T32)ch);
