REGISTERS
This section describes the HI-3110 registers. All register bits are active high. Unless otherwise indicated, all registers are reset
in software to the logic zero condition after Master Reset. For all registers, bit 7 is the most significant:
Power-On-Reset
Following power-on, the HI-5110 will automatically perform a Master Reset and return all registers to the default state.
Following reset, the device will default to Initialization Mode to allow programming of Control and Bit Timing Registers (see
following sections).
Note: Free-running counter registers, TIMERUB:TIMERLB are read with a single SPI Op-code (0xFA) as a 16-
