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”.

Function
RW
(b6-b0)
Nothing is assigned.
When write, set to “0”. When read, their contents are
indeterminate.
CPSR
Clock prescaler reset flag Setting this bit to “1” initializes the
prescaler for the timekeeping clock. ( ^RW
When read, its content is “0”.)
