S3C821A - S3C8-SERIES MICROCONTROLLES

General Description

Table 1-1.

P0.7 Pin Type I/O Pin Description 4-bit-programmable I/O port.

Pull-up resistors and open-drain outputs are software assignable.

Pull-up resistors are automatically disabled for output pins.

Key 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 A 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 six CPU clocks) can be assigned to specific interrupt levels. S3C821A/P821A.
