Timers and Rotary Decoder
This chapter describes the timers and rotary decoder included on the i.MX23. Programmable registers are
described in Section 22.4, “Programmable Registers.”
22.1 Overview
The i.MX23 implements four timers and a rotary decoder, as shown in Figure 22-1. The timers and
decoder can take their inputs from any of the pins defined for PWM, rotary encoders, or certain divisions
from the 32-kHz clock input. Thus, the PWM pins can be inputs or outputs, depending on the application.
