Features

— Capability to generate high quality sound, tone, or melody

• Interrupt controller

— All interrupts are maskable.

— Interrupt level of all internal modules is configurable.

— Four dedicated external interrupt IRQ signals (defined interrupt level; programmable edge,

level, and polarity).

• General-purpose I/O (GPIO) ports

— 93 total I/O ports in 12 groups with interrupt capability, all multiplexed with peripheral

functions.

— All ports are specially designed with dedicated internal pull-up and pull-down resistors.

• Multimedia card and secure digital (MMC/SD) host controller

— Compatible with the MMC system specification version 2.2

— Compatible with the SD Memory Card specification 1.0

— Ability to achieve maximum data rate with up to 10 cards; only 1 SD card is allowed

— Password protection of cards

— Multi-SD function support

— Error auto-detection for Response CRC and time-out and Access CRC and time-out errors

— Built-in 7 and 16 CRC generation and checking for command and data

— Built-in programmable frequency counter for MMC/SD host controller bus

— Maskable hardware interrupt for internal status and FIFO status indicator

— 16-bit internal data operation, 8 × 16-bit FIFO, and DMA interface

— Automatic operation pause when internal FIFO full, allowing flexible packet transaction for

dynamic DMA transfer

— Built-in 3-bit prescaler and 3-bit bus clock divider to maximize the performance of data

transaction between memory card and host

• Memory Stick host controller (MSHC)

— Built-in 8-byte (4-word) FIFO buffer for transmit and receive

— Built-in CRC circuit

— Support for internal or external serial clock source

— Built-in Serial Clock Divider: maximum 33.16 MHz serial data transfer rate

— DMA supported; DMA request condition is selectable based upon FIFO status

— Automatic command execution when an interrupt from the Memory Stick is detected (can be

turned on/off)

— RDY time-out period can be set by the number of serial clock cycles

— Interrupt can also be output to the core when a time out occurs

— Two built-in general-purpose input pins for detecting Memory Stick insertion/extraction

— 16-bit host bus access (byte access not supported)
