E1 Input value Use a ring counter consisting of 16 bits or more.
• 16-bit ring counter
00000000H  0000FFFFH  00000000H[pulse]
• 24-bit ring counter
00000000H  00FFFFFFH  00000000H[pulse]
• 32-bit ring counter
00000000H  FFFFFFFFH  00000000H[pulse]
However, set 32767 (7FFFH) or less for the pulse increment in
each instruction execution.
