MT90502_06 ZARLINK [Zarlink Semiconductor Inc], MT90502_06 Datasheet - Page 189

• Manufacturer Part Number: MT90502_06
• Description: Multi-Channel AAL2 SAR
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

Note: t1, t4, and t5 are dependent upon the last of cpu_cs and cpu_rd_ds to be asserted. t6 is dependent on the
first of cpu_cs and cpu_rd_ds to be de-asserted.
