10.1 Overview
10.1.1
• The timer interrupt (TMnINT) is generated when the values of timer counter register (TMnC, n=0 to 3) and timer data
• A timer configured by combining timer 0 and timer 1 or timer 2 and timer 3 can be used as a 16-bit timer.
• For the timer clock, the low-speed clock (LSCLK), high-speed time base clock (HTBCLK), or external clock can be
• A 16bit-timer 2 & 3 has clock frequency measurement mode, which can count HTBCLK and generates the timer
