Description
CE
Chip Enable, when low, enables the PPI for transfers.
DATA(31:0) and DTACK are tristated when CE is high.
Read/Write defines a PPI cycle. Read when high, write when
low.
Strobe is used for timing all PPI transfers. DATA(31:0) are
tristated when STB is high. Data valid setup is with respect
to the falling edge of STB and data valid hold is with respect
to rising edge of STB.
Data Acknowledge (open drain - sustained tristate). DTACK
is used to synchronize asynchronous transfers between the
host and the STA101. During write cycles, DTACK goes low
when data has been registered and then goes to high
impedance when the cycle has been completed. During read
cycles DTACK goes low when data bus is driven with the
valid data and then goes to high impedance when the cycle
has been completed.
Interrupt is used to trigger a host interrupt for any of the
defined interrupt events. Signal is active high.
