8.3.8 Timer Bypass
In this mode, the counter and prescaler cannot be enabled. However TGATE and
TOUTx can be used for I/O. This mode can be selected by programming the CR MODE
bits to 111.
TGATE can be used as a simple input port when the CR is configured as follows:
CR
TGATE AS A SIMPLE INPUT
X-Don’t care
When TGATE is asserted, the SR ON bit is set. When TGATE is negated, the ON bit is
cleared. The value of the TGL bit in the SR reflects the level of TGATE . TGATE can
also be used as an input port that generates interrupts on a low-to-high transition of
TGATE when the CR is configured as follows:
CR
TGATE AS AN INPUT/INTERRUPT
When TGATE is negated, the SR TG bit is set, and the programmed IRQx signal is
asserted to the CPU32. The TG bit can only be cleared by writing a one to this bit position.
The value of the SR TGL bit reflects the level of TGATE .
Additionally, TOUTx can be used as a simple output port when the CR is configured as
follows:
CR
TGATE AS A SIMPLE OUTPUT
SWR must be a zero to change the value of TOUTx. Changing the value of the CR OCx
bits determines the level of TOUTx as shown in Table 8-1.
