6.10 Hardware Divider (HDIV)
6.10.1 Overview
The hardware divider (HDIV) is useful to the high performance application. The hardware divider
is a signed, integer divider with both quotient and remainder outputs.
6.10.2 Features
 Signed (two’s complement) integer calculation
 32-bit dividend with 16-bit divisor calculation capacity
 32-bit quotient and 32-bit remainder outputs (16-bit remainder with sign extends to 32-bit)
 Divided by zero warning flag
 6 HCLK clocks taken for one cycle calculation
 Write divisor to trigger calculation
 Waiting for calculation ready automatically when reading quotient and remainder
