Timers

Purpose

• Basic read and set time
• Functionality for alarm interrupt handling.

Description

• The MCU has one hardware timer and four alarms.
• The timer is 64 bits, hence reading the full time requires two register accesses.
• Many timing application can get away with only reading the lower 32 bits, if roll-over is taken into account.
• SetTime should only be used for development/debugging purposes, since doing so may interfere with other processes using the timing features, including the alarms.
