BUSY_EN (Busy Enable). Controls the assertion of the BUSY# output during a download
initiated by a soft reset.
1: Enables the assertion of the BUSY# output
0: Disables the assertion of the BUSY# output
Upon the assertion of the RSTIN# input, this bit will be set automatically and the BUSY#
output signal will be asserted until the completion of the download process.
PU_DIS (Pull-up Disable). Controls the pull-up resistors D[15:8] as follows:
1: Always disable the pull-ups
0: Enable the pull-ups when IF_CFG = 0
TURBO. Activates turbo operation.
0: DiskOnChip is used in normal operation, without improved access time. Output buffers
1. DiskOnChip is used in Turbo operation. Output buffers are enabled immediately after the
Reserved for future use.
This register controls the behavior of certain output signals. This register is reset
by a hardware reset, not by entering Reset mode.

single transition on each bit.

Programmable Boot Block may result in additional noise and power dissipation due to
multiple transitions on the data bus.
