Data Sheet
Block 2 contains 2 timers/counters with a maximum resolution of f
CAPREL register supports capture and reload operation with extended functionality.
The following enumeration summarizes all features to be supported:

14.1
All three timers of block 1 (T2, T3, T4) can run in 4 basic modes, which are timer, gated
timer, counter and incremental interface mode, and all timers can either count up or
down.
Each timer has an input line (TxIN) associated with it which serves as the gate control in
gated timer mode, or as the count input in counter mode. The count direction (Up / Down)
may be programmed via software or may be dynamically altered by a signal at an
external control input line. An overflow/underflow of core timer T3 is indicated by the
output toggle latch T3OTL whose state may be output on related line T3OUT and on line
T3OFL. The auxiliary timers T2 and T4 may additionally be concatenated with the core
timer, or used as capture or reload registers for the core timer. Concatenation of T3 with
other timers is provided through line T3OFL.
The current contents of each timer can be read or modified by the CPU by accessing the
corresponding timer registers T2, T3, or T4, which are located in the non-bitaddressable
SFR space. When any of the timer registers is written to by the CPU in the state
immediately before a timer increment, decrement, reload, or capture is to be performed,
the CPU write operation has priority in order to guarantee correct results.
