Terms and Conditions of Sale only. Single full-duplex serial channel; on-chip DMA Controller. B supports multitasking applications Compatible with family controllers.

V-Series 13 The following relocatable assemblers are available: In all modes system clock rate must be 4. Commonly used commands and Nec AD-7201 P-ATA bits are accessed directly through control and status register O. Other functions are accessed indirectly with a register pOinter to minimize the address space that must be dedicated to the MPSCC.

Nec AD-7201 P-ATA Control and status register 2 are linked with the overall operation of the MPSCC and have different meanings when addressed through different channels. Each channel may then be programmed for separate use beginning with control register 4 to set the protocol mode for that channel.


The remaining registers may then be programmed in any order. Control Registers Control Register o Table 2.

After a hardware or software reset, the register pointer is set to zero. Therefore, the first control byte goes to control register O.

The pointer is then reset to 0 by setting the register pointer. This command has no effect and is used only to set the register pointer or issue a CRC command.

Any data currently in the transmitter or the transmitter buffer is destroyed. After sending the abort, the transmitter reverts to the idle phase flags.

When using the Tx byte count mode enable Os of CR1the Nec AD-7201 P-ATA abort command is automatically issued when an underrun condition occurs. This command has the same effect on a single channel as an external reset at pin 2.

A channel reset command to channel A rests the internal interrupt prioritization logic. This does not Nec AD-7201 P-ATA when a channel reset command is issued to channel B. All control registers associated with the channel to be reset must be reinitialized.


After a channel reset, wait at least four system clock cycles before writing new commands or Nec AD-7201 P-ATA to that channel. Enable Interrupt on Next Character ]: Issue this command at any time when operating the MPSCC in an interrupt on first received character mode. This command must be issued at the end of a message to reenable the interrupt logic Nec AD-7201 P-ATA the next received.

A pending transmitter buffer empty interrupt or OMA request can be reset without sending another character by issuing this command typically at the end of a message. A new transmitter buffer empty interrupt or OMA request is not made until another character has been loaded and transferred to the transmitter shift register or when, if operating in synchronous mode, the first CRC character has been sent.

This command resets a special receive condition interrupt.

It also reenables the parity.
