17.3 IO Mapping
Up to 16 I/Os (package dependent) can be routed to the AUX_PD I/O controller by configuring the MCU
I/O controller. This lets the sensor controller directly control I/Os independently of the MCU and the MCU
power modes used.
See Chapter 11, I/O Control, for more details on the mapping between AUX I/Os and digital I/Os.
17.4 Modules
17.4.1 Sensor Controller
17.4.1.1 Introduction
The sensor controller module is a proprietary, lightweight CPU optimized for low power. Some
architectural highlights include:
• Comprehensive 2-operand load/store RISC-style instruction set with high code density
• All instructions consist of one 16-bit opcode
• 8 general-purpose registers of configurable width up to 16-bit
