11 / 47 page 11 of 47 May 25, 2004 IDT 79RC32355 DMAP[2] O Low Drive Active DMA channel code. DMA debug enable is selected during reset using the boot configuration and overrides the selection of the Primary and Alternate functions. Primary function: General Purpose I/O, GPIOP[9]. 1st Alternate function: U1SINP. DMAP[3] O Low Drive Active DMA channel code. DMA debug enable is selected during reset using the boot configuration and overrides the selection of the Primary and Alternate functions. Primary function: General Purpose I/O, GPIOP[8]. 1st Alternate function: U1SOUTP. UART U0SOUTP I STI UART channel 0 serial transmit. Primary function: General Purpose I/O, GPIOP[0]. At reset, this pin defaults to primary function GPIOP[0]. U0SINP I STI UART channel 0 serial receive. Primary function: General Purpose I/O, GPIOP[1]. At reset, this pin defaults to primary function GPIOP[1]. U0RIN I STI UART channel 0 ring indicator. Primary function: General Purpose I/O, GPIOP[2]. At reset, this pin defaults to primary function GPIOP[2] if JTAG reset enable is not selected during reset using the boot configuration. 2nd Alternate function: JTAG boundary scan reset, JTAG_TRST_N. U0DCRN I STI UART channel 0 data carrier detect. Primary function: General Purpose I/O, GPIOP[3]. At reset, this pin defaults to primary function GPIOP[3]. U0DTRN O Low Drive UART channel 0 data terminal ready. Primary function: General Purpose I/O, GPIOP[4]. At reset, this pin defaults to primary function GPIOP[4] if CPU/DMA Sta- tus Mode enable is not selected during reset using the boot configuration. 2nd Alternate function: CPU or DMA transaction indicator, CPUP. U0DSRN I STI UART channel 0 data set ready. Primary function: General Purpose I/O, GPIOP[5]. At reset, this pin defaults to primary function GPIOP[5].

U1SINP I STI UART channel 1 serial receive. Primary function: General Purpose I/O, GPIOP[9]. At reset, this pin defaults to primary function GPIOP[9] if DMA Debug enable is not selected during reset using the boot configuration. 2nd Alternate function: DMA channel, DMAP[2]. U1DTRN O Low Drive UART channel 1 data terminal ready. Primary function: General Purpose I/O, GPIOP[10]. At reset, this pin defaults to primary function GPIOP[10] if ICE Interface enable is not selected during reset using the boot configuration. Alternate function: PC trace status bit 0, EJTAG_PCST[0]. U1DSRN I STI UART channel 1 data set ready. Primary function: General Purpose I/O, GPIOP[11]. At reset, this pin defaults to primary function GPIOP[11] if ICE Interface enable is not selected during reset using the boot configuration. 2nd Alternate function: PC trace status bit 1, EJTAG_PCST[1]. U1RTSN O Low Drive UART channel 1 request to send. Primary function: General Purpose I/O, GPIOP[12].
