Function
MTR(213) outputs the selection signals to bits 00 to 07 of O, reads the data in order from bits 00 to 07
of I, and stores the 64 bits of data in the 4 words D through D+3. MTR(213) reads the status of the 64-
bit matrix every 24 CPU Unit cycles. The One Round Flag (bit 08 of O) is turned ON for one cycle in
every 24 cycles after each of the selection signals has been turned ON.
External Connections
