Program/Data RAM

This section describes the FX2LP18 RAM.

3.10.1Size

The FX2LP18 has 16 kBytes of internal program/data RAM. No USB control registers appear in this space.

Memory maps are shown in Figure 3-3and Figure 3-4.

3.10.2Internal Code Memory

This mode implements the internal 16-kByte block of RAM (starting at 0) as combined code and data memory. Only the internal 16 kBytes and scratch pad 0.5 kBytes RAM spaces have the following access:

•USB download

•USB upload

•Set-up data pointer

•I2C interface boot load

This section describes the FX2LP18 Endpoint RAM.

3.12.1Size

• 3 × 64 bytes (Endpoints 0, 1)

• 8 × 512 bytes (Endpoints 2, 4, 6, 8)

3.12.2Organization

• EP0

• Bidirectional endpoint zero, 64-byte buffer

• EP1IN, EP1OUT

• 64-byte buffers: bulk or interrupt

• EP2, 4, 6, 8

•Eight 512-byte buffers: bulk, interrupt, or isochronous. EP4 and EP8 can be double buffered, while EP2 and 6 can be double, triple, or quad buffered. For high-speed endpoint configuration options, see Figure 3-5.

3.12.3Set-up Data Buffer

A separate 8-byte buffer at 0xE6B8-0xE6BF holds the set-up data from a CONTROL transfer.

3.12.4Endpoint Configurations (High-speed Mode)

Endpoints 0 and 1 are the same for every configuration. Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can be either BULK or INTERRUPT. The endpoint buffers can be configured in any one of the 12 configurations shown in the
