V2.0, 2000-07

All three timers of block GPT1 (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 alternate input function pin (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 pin. Each overflow/underflow of core timer

T3 is latched in the toggle FlipFlop T3OTL and may be indicated on an alternate output

function pin. 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.

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.
