Shared functions include three external interrupt inputs and I/O for timer.

Features

are: — Efficient register-oriented architecture — Selectable CPU clock sources — Idle and Stop power-down mode release by interrupt — Built-in basic timer with watchdog function The sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum of four CPU clocks) can be assigned to specific interrupt levels. S3C8639/C863A/P863A MICROCONTROLLERS S3C8639/C863A/P863A single-chip 8-bit microcontrollers are based on the powerful SAM8 CPU architecture. The internal register file is.
