... ICLK. The MTD658 output REQOUT to inform Inter-Bus Interface that it need the Inter-Bus right. When IACKB is asserted by Inter-Bus master after REQOUT asserted, the MTD658 which asserted REQOUT will get the bus right and put the transmit data into IDATA.

... MYSON TECHNOLOGY REQOUT , but IACKB is asserted, means this MTD658 can get data from IDATA bus. When only one MTD658 output REQOUT to Inter-Bus Interface, IACKB will be asserted by Inter-Bus master device, If larger than two MTD658’ s REQOUT were asserted, Inter-Bus master will not assert IACKB , but will assert ICOLB to inform all the connected MTD658s. The Inter-Bus interface can also be programmed to EXT_ARB mode, using LEDDAT pin’ ...
