The bits of this operand have the following meaning: ========== ========= ================================================ ============ High Bits Low Bits Description Value Range ========== ========= ================================================ ============ 15:14 3:0 VM_CNT: vector memory operations count. 0..63 \- 6:4 EXP_CNT: export count. 0..7 \- 11:8 LGKM_CNT: LDS, GDS, Constant and Message count. 0..15 ========== ========= ================================================ ============ This operand may be specified as one of the following: * An :ref:`integer_number` or an :ref:`absolute_expression`. The value must be in the range 0..0xFFFF. * A combination of *vmcnt*, *expcnt*, *lgkmcnt* and other values described below. ====================== ====================================================================== Syntax Description ====================== ====================================================================== vmcnt(<*N*>) A VM_CNT value. *N* must not exceed the largest VM_CNT value. expcnt(<*N*>) An EXP_CNT value. *N* must not exceed the largest EXP_CNT value. lgkmcnt(<*N*>) An LGKM_CNT value. *N* must not exceed the largest LGKM_CNT value. vmcnt_sat(<*N*>) A VM_CNT value computed as min(*N*, the largest VM_CNT value). expcnt_sat(<*N*>) An EXP_CNT value computed as min(*N*, the largest EXP_CNT value). lgkmcnt_sat(<*N*>) An LGKM_CNT value computed as min(*N*, the largest LGKM_CNT value). ====================== ====================================================================== These values may be specified in any order. Spaces, ampersands and commas may be used as optional separators. *N* is either an :ref:`integer number` or an :ref:`absolute expression`.
