Note: Infra-Red generates two interrupts: at the rising edge and at the falling edge,
for IR signal decoding.
(PIO29)
(PIO21)
Note: Instead of KM616V1000B,
IS61LV25616-12T (256K x 16 bit
4M) can be stuffed for debug.
(256K x 16Bit FLASH)
(PIO20)
(128KBytes SRAM)
The RM1_WR_N is
delayed by 2 gates
because the data
should be stable
during the falling
edge of the WRITE
signal.
