CPU_DATA[15:0
Address Setup - (R/W, AEM and
CPU_ADD[20:1] VALID) to (CS and DS
asserted)
Address Hold - (CS or DS de-asserted)
to (AEM, CPU_ADD[20:1] and R/W
INVALID)
DTACK High - CS asserted to DTACK
driven high
DTACK Delay - (CS and DS asserted)
to DTACK asserted
DTACK High-Impedance - CS de-
asserted to DTACK high-impedance
Data Input Setup - CPU_DATA[15:0]
VALID to (CS and DS asserted)
Data Input Hold - (CS or DS de-
asserted) to CPU_DATA[15:0] INVALID
Note 1: MCLK = 66 MHz (15.2 ns)
Note 2: Both CS and DS must be asserted for a write cycle to occur. A write cycle is completed when either CS or DS is de-asserted.
Note 3: There should be a minimum of 3 MCLK periods between CPU accesses (CS de-asserted), to allow the MT90520 to recognize the
accesses as separate (i.e., CS must be de-asserted for 3 MCLK cycles between CPU accesses).
