6.3.5 Timer channel enable status register m (TEm)
The TEm register is used to enable or stop the timer operation of each channel.
Each bit of the TEm register corresponds to each bit of the timer channel start register m (TSm) and the timer channel
stop register m (TTm). When a bit of the TSm register is set to 1, the corresponding bit of this register is set to 1. When a
bit of the TTm register is set to 1, the corresponding bit of this register is cleared to 0.
The TEm register can be read by a 16-bit memory manipulation instruction.
The lower 8 bits of the TEm register can be set with a 1-bit or 8-bit memory manipulation instruction with TEmL.
Reset signal generation clears this register to 0000H.
