For the source data, the seconds is designated in bits 00 through 07 and the
minutes is designated in bits 08 through 15 of S. The hours is designated in
S+1. The maximum is thus 9,999 hours, 59 minutes, and 59 seconds.
The results is output to R and R+1. The maximum obtainable value is
35,999,999 seconds.
Flags ER: S and S+1 or R and R+1 are not in the same data area.
S and/or S+1 do not contain BCD.
Number of seconds and/or minutes exceeds 59.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: Turns ON when the result is zero.
Example When 00000 is OFF (i.e., when the execution condition is ON), the following
instruction would convert the hours, minutes, and seconds given in HR 12
and HR 13 to seconds and store the results in DM 0100 and DM 0101 as
shown.

Limitations Can be performed with the CPU11-E only. S and S+1 must be within the
same data area. R and R+1 must be within the same data area. S and S+1
must be BCD and must be between 0 and 35,999,999 seconds.
Description STH(66) is used to convert time notation in seconds to an equivalent in hour-
s/minutes/seconds.
The number of seconds designated in S and S+1 is converted to hours/minu-
tes/seconds and placed in R and R+1.
