NOTE - in this document we use following symbols to mark special or variable states:
- fil - MREG bit is equal to
filparameter of set_mode command. - K - MREG bit value is unchanged by set_mode - so it keeps its value that it had before set_mode command was executed.
- CF - if current source was enabled prior to entering this mode (Re6~9 @ D1642 were on), Re2 @ D1639 will be switched off; otherwise behaves like
fil. - CS - if one of Re13,14 was enabled prior to entering this mode, both Re13,14 will be turned on, disconnecting input terminals H:L from the current shunts and shorting them through diodes D5,D6.
