Table 4-4. Individual FIFO/GPIF Interrupt Sources
If Autovectoring is enabled (AV4EN = 1 in the INTSETUP
register), the FX1 substitutes its INT4VEC byte. Therefore, if
the high byte (“page”) of a jump-table address is preloaded at
location 0x0054, the automatically-inserted INT4VEC byte at
0x0055 will direct the jump to the correct address out of the 14
addresses within the page. When the ISR occurs, the FX1
pushes the program counter onto its stack then jumps to
address 0x0053, where it expects to find a “jump” instruction
to the ISR Interrupt service routine.

Priority
If the external clock is powered at the same time as the CY7C64713/4 and has a stabilization wait period, it must be added to the 200 µ s.

4.9.1
The input pin, RESET#, will reset the FX1 when asserted. This
pin has hysteresis and is active LOW. When a crystal is used
with the CY7C64713/4 the reset period must allow for the
stabilization of the crystal and the PLL. This reset period
should be approximately 5 ms after VCC has reached 3.0
Volts. If the crystal input pin is driven by a clock signal the
internal PLL stabilizes in 200 µs after VCC has reached
3.0V
reset applied during operation. A power on reset is defined as
the time reset is asserted while power is being applied to the
circuit. A powered reset is defined to be when the FX1 has
previously been powered on and operating and the RESET#
pin is asserted.
Cypress provides an application note which describes and
recommends power on reset implementation and can be found
on the Cypress web site. While the application note discusses
the FX2, the information provided applies also to the FX1. For
more information on reset implementation for the FX2 family
of products visit the http://www.cypress.com.
