BUS RETRY
Note 1 Depending upon the mode the SONIC-16 will assert and deassert HOLD from the rising or falling edge of BSCK
Note 2 Unless Latched Bus Retry mode is set (LBR in the Data Configuration Register Section 4 3 2) BRT must remain asserted until after the Th state If
Latched Bus Retry mode is used BRT does not need to satisfy T42
Note 3 T41 is for synchronous bus retry and T41a is for asynchronous bus retry (see Section 4 3 2 bit 15 Extended Bus Mode) Since T41a is an asynchronous
setup time it is not necessary to meet it but doing so will guarantee that the bus exception occurs in the current memory transfer not the next
Note 4 BGACK is driven high for approximately
