III PERIPHERAL BLOCK: INTRODUCTION

III-1 INTRODUCTION

The C33 peripheral block consists of a prescaler, six 8-bit programmable timer channels, six 16-bit programmable timer channels including watchdog timer and event counter functions, four serial interface channels, input and I/O ports, a low-speed (OSC1) oscillation circuit, and a clock timer, mobile access interfaces (one PHS, PDC, and HDLC channel each).
