(a) When local devices in a subroutine program are enabled
When SM776 (Enable/disable local device at CALL) is turned on, the processing time listed in the following
table is required for each subroutine call. Each n, N1, N2, N3, and N4 in the table indicates the following.
• n: Number of local device points (unit: K words)
• N1: Number of devices that specified a local device
• N2: Number of word device points that specified a local device (except index register)
• N3: Number of bit device points that specified a local device
• N4: Number of index register points that were specified as a local device
