I/O access timing

This section explains the input (X) and output (Y) data transfer timings of the C Controller
module.

(1) Input (X) loading timing

The C Controller module loads input (X) data at one of the following timings.

(2) Output (Y) writing timing

The C Controller module writes output (Y) data at one of the following timings.
Remark
• When a bus interface function (such as the QBF_X_In_BitEx function) is
executed in the user program
• When input (X) data are read out from a peripheral device (such as GOT)
• When a bus interface function (such as the QBF_Y_Out_BitEx function) is
executed in the user program
• When output (Y) data are written from a peripheral device (such as GOT)
1. For details of the bus interface functions, refer to the following.
C Controller User's Manual (Utility Operation, Programming)
2. For processing time of the bus interface functions, refer to the following.
