R/W Default Description
R/W 0x00 Free RunningTimer 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. Note:Atimer overrun is not
flagged by the HI-3110. The timer is clocked by the HI-3110 bit clock and continuously
increments by the bit rate (default). The user may program the timer to 2, 4 or 8 bit clocks by
setting theTTDIV1:0 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 (seeTable 1, SPI Instruction Set).
