Function
RW
The timer starts counting by setting ^RW
this bit to “1” while the TMOD1 to
TMOD0 bits of TAiMR register (i =
RW
0 to 4) = ‘102’ (= one-shot timer
RW
mode) and the MR2 bit of TAiMR
register = “0” (=TAiOS bit enabled). RW
When read, its content is “0”.
RW
Reserved bit
(b6)
Should be set to “0”.
