1.1.1 Dead Zone Exists in Level-Triggered Start/Reset Condition When an ERS Signal Is Generated Due to an SFR Access
When a level-triggered Start/Reset condition (START = ‘b11 or RESET =
‘b01) is triggered by an ERS signal generated by an SFR access such
as TUxyPRL_Write or TUxyTMRL_Read or TUxyCRL_Read (TUxyERS = 0x3E or 0x3F), there exists
a dead zone in which subsequent SFR accesses will be missed. This dead zone is the
period between the ZIF flag being set and the timer starting to count again. This can be
monitored by checking either the RUN status bit or the level output of the timer.
Work around
The user must wait for the timer to start counting before accessing the period, counter and capture registers again.
