Notes:
1. Burst access starts with a rising CLK edge and when ADV# is active.
2. Configurations register 6 must be always set to 1 (CR6 = 1). Burst starts and data outputs on the rising CLK edge.
3. CR [13-10] = 0001 or three clock cycles
4. CR [13-10] = 0010 or four clock cycles
5. CR [13-10] = 0011 or five clock cycles

Burst CLK Edge Data Delivery
The device is capable of delivering data on either the rising or falling edge of CLK.
To deliver data on the rising edge of CLK, bit 6 in the Control Register (CR6) is
set to 1. The default configuration is set to the rising edge.
Burst Data Hold Control
The device is capable of holding data for one CLKs. The default configuration is
to hold data for one CLK and is the only valid state.
Asserting RESET# During A Burst Access
If RESET# is asserted low during a burst access, the burst access is immediately
terminated and the device defaults back to asynchronous read mode. Refer to
“RESET#: Hardware Reset Pin” on page 18
function.
The device contains a Configuration Register for configuring read accesses. The
Configuration Register is accessed by the Configuration Register Read and the
Configuration Register Write commands. The Configuration Register does not oc-
