Free Running Timer Upper Byte, bits <15:8>.
The 16-bit free-running timer starts counting from zero following RESET. The timer counts
linearly up to 0xFFFF and then wraps around to 0x0000.

increments by the bit rate (default). The user may program the timer to 2, 4 or 8 bit clocks by
setting the TTDIV1:0 bits in Control Register 0, CTRL0.
The timer may be reset by the host after any interrupt condition (e.g. reading the receive buffer,
transmit FIFO empty, etc), by issuing an SPI instruction (see Table 1, SPI Instruction Set).
