Assuming MCU instruction uses A[15:0] to access memory space.
If A[15]=0 -> mapped to internal SRAM ,then
If A[14]=0, mapped to lower 16KB (ZRAM)
If A[14]=1, mapped to upper 16KB (IPMH/IPMM/IPML/IDMH/IDMM/IDML/VRAM) when they are
mapped into MCU memory space. Additional three extended bits of SRAM Page Register (IO index=0x05) are
used to decode which page to access.

on-chip VRAM (Video RAM)
IPM/IDM can map to MCU memory space in 8K unit.
If A[15]=1 -> External address pin A25~A15 are IO mapped at 01h and 02h for EMA15-25. While
EMA26-28 are used to decode CE0- ~ CE6-.
CE0- is used to access boot code from ROM/MASK/NOR-type Flash
CE1- to CE6- can be configured to access ROM, or RAM or NAND-type Flash

Actions Semiconductor Co.,LTD
5.4 USB1.1 Interface
Compliant with USB SPEC 1.1. Certified by USB IF.
4 endpoints are provided. Support bulk, control, interrupt and isochronous transfer mode . Endpoint 1 and
endpoint 2 employ two independent FIFOs for bulk or isochronous transfers. Endpoint 0 and endpoint 3 have
8 bytes maximum packet size. There are 4 interrupt requests for each endpoint respectively. Generally, this
setting should be satisfying for most practical needs.
5.5 MPEG Decoder
With system software, ATJ2073 is competent for MPEG 1/2/2.5 Layer I/II/III decode.
Sample rates (SR) and bit rates (BR) supported is shown as the following table.
