I have a KL03 board and I can generate a timer using the 1kHz LPO. However, I wanted to know if I can generate a 1MHz timer using a different clock as I am trying to interface with an HC-SR04 Ultrasound sensor.

Hi,

LPTMR  has four clock source. MCGIRCLK,  LPO, ERCLK32K, OSCERCLK.

You can use MCGIRCLK to generate 1 Mhz.

Have a great day,
TIC
