9.7 Timer configuration registers
9.7.1 TControl
Control register of the timer section.
The TControl implements a special functionality to avoid the not intended modification of
bits.
Bit 3..0 indicates, which bits in the positions 7..4 are intended to be modified.
Example: writing FFh sets all bits 7..4, writing F0h does not change any of the bits 7..4
