Bit 7-0 GPIFA7:0 Lower 8 bits of GPIF Address
Data written to this register immediately appears as the bus address on the ADR[7:0] pins.
15.12.6 GPIF Flowstate Registers
For complete Flowstate / UDMA information, please contact the Cypress Semiconductor Applica-
tions Department.
Any one (and only one) of the seven GPIF states in a waveform can be programmed to be the flow
state. This register defines which state, if any, in the next invoked GPIF waveform will be the flow
state.
Bit 7 FSE Global Flow State Enable
Global enable for the flow state. When it is disabled all flow state registers are don’t care and
the next waveform invocation will not cause a flow state to be used.
Bit 2-0 FS[2:0] Flow State Selection
Defines which GPIF state is the flow state. Valid values are 0-6.\
