After forcing the output level to either active or inactive, the TOAAn1
(TOAAn0) maintains this level (i.e. no toggling afterwards) until the
TAAnOS1 (TAAnOS0) and TAAnOR1 (TAAnOR0) are cleared to standard
operation.
2.
The forcing of an output level is executed at the time of the next upcoming
toggle event, while the freeze becomes effective immediately.

Writing to TAAnIOC4 is also possible, when TAAnCTL0.TAAnCE = 1.

The TAAnIOC4 register can be used in the interval mode or the free
running mode. In other modes set this register to 00H.

In the free running mode, the setting's of the TAAnIOC4 register becomes
effective only if the compare function is selected. When the capture
function is selected, it is invalid.
