TIMER T2 OPERATION IN IDLE MODE
Timer T2 has a special mode that allows it to be operated in IDLE mode. To use this mode, T2 must be
configured as a high speed timer, by setting T2HS = 1, and, also, configured to run in the IDLE mode by setting
the T2IDLE bit to 1 in the HSTCR register. Table 18 shows the modes of operation allowed for T2 during the
IDLE mode. All the T2 modes are allowed except the following:
• Using the instruction cycle clock (t_c)
• PWM: TxA Toggle
T2 should not be left in this special mode when entering HALT. The T2IDLE bit must be reset to 0 before
entering the HALT mode to ensure that T2 remains in the same state when exiting HALT as it was prior to
entering HALT.
