® SC01/SC02/SC11/SC12 IPC GmbH PIN FUNCTIONS Pins That Are Used by Emulators The following pins are used by emulators for debugging purposes: TxD0, RxD0 Pin Terminology The following terms are used to describe the pins: Input (I) - An input-only pin. Output (O) - An output-only pin.
® SC01/SC02/SC11/SC12 IPC GmbH Programmable I/O Pins Pin Name Type Function PIO[0..13] I/O Programmable I/O Pins (input/output, asynchronous, open-drain) The IPC@CHIP® family microcontroller provides 14 individually programmable I/O pins. Each PIO can be programmed with the following attributes: PIO function (enabled/disabled), direction (input/output), and weak pullup or pulldown.
® SC01/SC02/SC11/SC12 IPC GmbH Interrupts Pin Name Type Function INT[0,2-4] I Maskable Interrupt Request (input,asynchronous) These pins indicate to the microcontroller that an interrupt request has occurred. If the INT pin is not masked, the microcontroller transfers program execution to the location specified by the corresponding INT vector in the microcontroller interrupt vector table.
® SC01/SC02/SC11/SC12 IPC GmbH 10Base-T Interface Pin Name Type Function TPTX[+,-] O Twisted Pair Driver (outputs) These two outputs provide the TP drivers with pre-distortion capability TPRX[+,-] I Twisted Pair Receive (inputs). A differential receiver tied to the receive transformer pair of the twisted-pair wire.
® SC01/SC02/SC11/SC12 IPC GmbH Pin Name Type Function DRQ[0..1] I DMA Request (input, synchronous, level-sensitive) These pins indicate to the microcontroller that an external device is ready for DMA channel 0 or 1 to perform a transfer. DRQ0 is edge-triggered and internally synchronized. DRQ is not latched and must remain active until serviced.

® SC01/SC02/SC11/SC12 IPC GmbH with all hardware interrupts, the IF (interrupt flag) is cleared when the processor takes the interrupt, disabling the maskable interrupt sources. However, if maskable interrupts are re-enabled by software in the NMI interrupt service routine, via the STI instruction for example, the fact that an NMI is currently in service does not have any effect on the priority resolution of maskable interrupt requests.
® SC01/SC02/SC11/SC12 IPC GmbH FUNCTIONS THAT ARE MUTUAL EXCLUSIVE The IPC@CHIP® family microcontroller provides a lot of different functions by several multi-function pins. Choosing one function will result in disabling other functions. The following table shows, which functions are mutual exclusive. Pin Name Function Exclusion...
® SC01/SC02/SC11/SC12 IPC GmbH SYSTEM OVERVIEW IPC@CHIP® family microcontroller has a system configuration based on the ISA architecture with some changes: No ISA-Bus, no Video-Interface, no Keyboard Interface, programming of Serial Ports, DMA, PIC and Timer is different from standard IBM PC. This section provides an overview of the system memory configuration and basic I/O.
