Section Page Description 16.4 SCIF Interrupts 550 Description amended When the TDFE flag in the serial status register (SCSSR) is set to 1, a TXI interrupt request is generated. The DMAC can be activated and data transfer performed when this interrupt is generated. When data exceeding the transmit trigger number is written to the transmit data register (SCFTDR) by the DMAC, 1 is read from the TDFE flag, after which 0 is written to it to clear it. When the RDF flag in SCSSR is set to 1, an RX

Cautions Keep safety first in your circuit designs! 1. Renesas Technology Corp. puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflam

General Precautions on Handling of Product 1. Treatment of NC Pins Note: Do not connect anything to the NC pins. The NC (not connected) pins are either not connected to any of the internal circuitry or are used as test pins or to reduce noise. If something is connected to the NC pins, the operation of the LSI is not guaranteed. 2. Treatment of Unused Input Pins Note: Fix all unused input pins to high or low level. Generally, the input pins of CMOS products are high-impedance input pins. If unuse
