MKY43 CUnet Master/Slave IC
This is a master and slave IC compatible with CUnet. It can be connected to the CPU using an 8 or 16-bit bus for your use.
【512-byte Shared Memory】 The 512-byte shared memory consists of 64 blocks (1 block is 8 bytes). This 512-byte shared memory is composed of a "self-occupied area" that can only be written to by the CPU connected to the self (CUnet IC) and an area where input data from other CUnet ICs is copied. 【Buffer for Mail Function】 The buffer for the mail function consists of two receive buffers and one send buffer, each of which is 256 bytes. 【Communication Control Register】 This is a register that controls communication such as starting communication, error checking, and sending and receiving mail. By simply accessing this register, it is possible to easily control CUnet communication. Additionally, the MKY43 has two interrupt terminals. It realizes various interrupt functions such as shared memory update interrupts, mail sending interrupts, mail receiving completion interrupts, specific terminal participation interrupts, specific terminal departure interrupts, and communication error occurrence interrupts.
