NuMicro^™ M052/M054BN Data Sheet
1/T0. For example:
HCLK = 50 MHz, PWM_CLK = 25 MHz, Interrupt latency is 900 ns
So the maximum capture frequency will is 1/900ns ≈ 1000 kHz
6.6.2 Features
6.6.2.1 PWM function features:
PWM group has two PWM generators. Each PWM generator supports one 8-bit prescaler, one
clock divider, two PWM-timers (down counter), one dead-zone generator and two PWM outputs.
 Up to 16 bits resolution
 PWM Interrupt request synchronized with PWM period
 One-shot or Auto-reload mode PWM
 Up to 2 PWM group (PWMA/PWMB) to support 8 PWM channels
6.6.2.2 Capture Function Features:
 Timing control logic shared with PWM Generators
 8 capture input channels shared with 8 PWM output channels
 Each channel supports one rising latch register (CRLR), one falling latch register (CFLR)
and Capture interrupt flag (CAPIFx)
