describes the HOSTDP A/C Host Write Cycle timing
HOST_ADDR/HOST_CE Setup
before HOST_WR falling edge
HOST_ADDR/HOST_CE Hold
after HOST_WR rising edge
HOST_WR pulse width low
(ACK mode)
HOST_WR pulse width low
(INT mode)
HOST_WR pulse width high
or time between HOST_WR
rising edge and HOST_RD
falling edge
HOST_WR rising edge delay
after HOST_ACK rising edge
(ACK mode)
Data Hold after HOST_WR rising edge 2.5
Data Setup before HOST_WR
rising edge
HOST_ACK falling edge after HOST_CE
asserted (ACK mode)
HOST_ACK low pulse-width for Write
access (ACK mode)
SCLK
. It is not measured because the number of SCLK cycles for which HOST_ACK is low depends on the Host DMA FIFO
