20.11.2 Processing Time of Macro Service
568
Macro service processing time differs depending on the type of the macro service, as shown in Table 20-8.
Remarks 1. IRAM: internal high-speed RAM
2. In the following cases in the other data areas, add the number of clocks specified below.
3. If MSC = 0 with type A, B, or C, add 1 clock.
4. With type C, add the following value depending on the function to be used and the status at that time.
• If the data size is 2 bytes with IROM or IRAM, and the data is located at an odd address: 4 clocks
• If the data size is 1 byte with EMEM: number of wait states for data access
• If the data size is 2 bytes with EMEM: 4 + 2n (where n is the number of wait states per byte)
• Ring control: 4 clocks. Adds 7 more clocks if the ring counter is 0 during ring control.
