Note: Mobile DiskOnChip G3 does not support MultiBurst write operations.
MultiBurst operation is controlled by 5 bits in the MultiBurst Mode Control register: BURST_EN,
CLK_INV, LATENCY, HOLD and LENGTH. For full details on this register, please refer to
Section 7.
MultiBurst mode read cycles are supported via the CLK input, which is enabled by setting the
BURST_EN bit in the MultiBurst Mode Control register.
To determine whether the rising or falling edge of the CLK input is sampled (called CLK0), the
CLK_INV bit in the MultiBurst Mode Control register must be specified. When the CLK_INV bit
is set to 0, CE# and OE# are sampled on the rising edge of CLK; when the CLK_INV bit is set to 1,
sampling is done on the falling edge of CLK.
Notes: 1. When the CLK_INV bit is set to 1, sampling is done on the falling edge of CLK, and an
