The CPM1 command mask is defined for use with the standard CPM1 command register as described in the user's manual: 0 |1 3|4 7|8 11|12 14| 15| RST| - |OPCODE|CH_NUM| - |FLG|
In the QMC extension the CPM1 command register is redefined (QMC supplement user's manuel) with the following mapping: 0 |1 3|4 7|8 13|14| 15| RST|QMC OPCODE| 1110|CHANNEL_NUMBER| -|FLG|
Extend the check command mask in order to support both the standard CH_NUM field and the QMC extension CHANNEL_NUMBER field.
