CCS
When the execution condition is OFF, CCS(173) is not executed. When the ex-
ecution condition is ON, CCS(173) records the current status of the Arithmetic
Flags in the CPU for later retrieval by the CCL(172) instruction.
Refer to the table in 5-28-1 LOAD FLAGS: CCL(172) for the Arithmetic Flags
recorded by CCS(173).
When CCS(173) is executed, it records over the data recorded by the previous
CCS(173) instruction.
No flags are affected by CCS(173).
When CIO 000000 is ON in the following example, the status of all the arithmetic
flags is stored in memory for possible later retrieval.

S: 1
REGL S
When the execution condition is OFF, REGL(175) is not executed. When the ex-
ecution condition is ON, REGL(175) copies the data from S, S+1, and S+2 to
data registers DR0, DR1, and DR2, and copies the data from S+3, S+4, and S+5
to index registers IR0, IR1, and IR2.
Refer to page 101 for general precautions on operand data areas.
Content of *DM word is not BCD when set for BCD.
ER (A50003):
When CIO 000000 is ON in the following example, the contents of words
D10000 through D10005 is copied to the data and index registers.
