HTBDR is a special function register (SFR) to set the divide ratio of the 4-bit, 1/n counter.
[Description of Bits]
*1: Indicates the frequency when the high-speed oscillation clock, HSCLK, is 4096 kHz.
HTD3
Initial value
The HTD3-HTD0 bits are used to set the frequency divide ratio of the 4-bit, 1/n counter. The frequency divide
ratios selectable include 1/1 to 1/16.
