... CY7C008/18, 1FFFF for the CY7C009/19) is the mailbox for the right port and the second-highest memory location (FFFE for the CY7C008/18, 1FFFE for the CY7C009/19) is the mailbox for the left port. When one port writes to the other port’s mailbox, an interrupt is generated to the owner. The interrupt is reset when the owner reads the contents of the mailbox ...
