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 9.7.2 T0Control Control register of the Timer0. Table 75. TControl register (address 0Eh) Bit 7 6 5 4 3 2 1 0 Symbol T3Running T2Running T1Running T0Running T3Start StopNow T2Start StopNow T1Start StopNow T0Start StopNow Access rights dy dy dy dy w w w w Table 76. TControl bits Bit Symbol Description 7 T3Running Indicates Timer3 is running.If the bit T3startStopNow is set, this bit and the timer can be started/stopped 6 T2Running Indicates Timer2 is running. If the bit T2startStopNow is set, this bit and the timer can be started/stopped 5 T1Running Indicates tTmer1 is running. If the bit T1startStopNow is set, this bit and the timer can be started/stopped 4 T0Running Indicates Timer0 is running. If the bit T0startStopNow is set, this bit and the timer can be started/stopped 3T3StartStop Now The bit 7 of TControl T3Running can be modified if set 2T2StartStop Now The bit 6of TControl T2Running can be modified if set 1T1StartStop Now The bit 5of TControl T1Running can be modified if set 0T0StartStop Now The bit 4 of TControl T0Running can be modified if set Table 77.
