ST10R172LT1 16位微控制器TQFP-100封装

16-bit low voltage ROMless MCU

ST10R172LT1 概述

The architecture of the ST10R172L supports several mechani*s for fast and flexible response to the service requests that can be generated from various sources, internal or external to the microcontroller. Any of these interrupt requests can be programmed to be serviced, either by the Interrupt Controller or by the Peripheral Event Controller (PEC).

In a standard interrupt service, program execution is suspended and a branch to the interrupt service routine is performed. For a PEC service, just one cycle is ‘stolen’ from the current CPU activity. A PEC service is a single, byte or word data transfer between any two memory locations, with an additional increment of either the PEC source or the destination pointer. An individual PEC transfer counter is decremented for each PEC service, except in the continuous transfer mode. When this counter reaches zero, a standard interrupt is performed to the corresponding source-related vector location. PEC services are very well suited, for example, to the tran*ission or reception of blocks of data. The ST10R172L has 8 PEC channels, each of which offers fastinterrupt-driven data transfer capabilities.A separate control register which contains an interrupt request flag, an interrupt enable flag and an interrupt priority bitfield, exists for each of the possible interrupt sources. Via its related register, each source can be programmed to one of sixteen interrupt priority levels. Once having been accepted by the CPU, an interrupt service can only be interrupted by a higher priority service request. For standard interrupt processing, each of the possible interrupt sources has a dedicated vector location. Fast external interrupt inputs are provided to service external interrupts with high precision requirements. These fast interrupt inputs, feature programmable edge detection (rising edge, falling edge or both edges). Software interrupts are supported by means of the ‘TRAP’ instruction in combination with an individual trap (interrupt) number.
