Frequently used MCC05v2 RDY check is coded as macroinstruction so that the program may be simplified.
#define xmccrdy() while(inp(XMCCST1) & 0x01) /* X-AXIS MCC05v2 READY WAIT */
#define ymccrdy() while(inp(YMCCST1) & 0x01) /* Y-AXIS MCC05v2 READY WAIT */
#define zmccrdy() while(inp(ZMCCST1) & 0x01) /* Z-AXIS MCC05v2 READY WAIT */
#define amccrdy() while(inp(AMCCST1) & 0x01) /* A-AXIS MCC05v2 READY WAIT */
Although the X axis is taken as an example in the following, the same applies to the Y, Z and A axes, too.
RAM area used in the program is defined as follows.
/******************************/

UC urate; /* UP RATE No. */
UC drate; /* DOWN RATE No. */
