SECTION 10

Using IORD and IOWR Instructions

The IORD and IOWR instructions are enabled with the C200HE, C200HG, or C200HX PCs.
These instructions make it possible to read data from the DM area allocated to the High-speed Counter Unit when it is
turned ON or restarted, change the present counter value, or change values set in the High-speed Counter Unit.
The IORD and IOWR instructions can be used only if word n+6 bit 06 is set to 0 (i.e., the High-speed Counter Unit is
not operating).
