Register initial setting
TPnCTL0 register
(TPnCKS0 to TPnCKS2 bits)
TPnCTL1 register,
TPnIOC0 register,
TPnIOC2 register,
TPnCCR0 register,
Initial setting of these registers
is performed before setting the
TPnCE bit to 1.
The TPnCKS0 to TPnCKS2 bits can
be set at the same time when counting
has been started (TPnCE bit = 1).
The counter is initialized and counting
is stopped by clearing the TPnCE bit to 0.
