系列: *
ROUND( (Required Divisor - TRUNC (Required Divisor) )*16)/16 + TRUNC (Required Divisor), where
DLM = TRUNC( Required Divisor) >> 8
DLL = TRUNC (Required Divisor) & 0xFF
DLD = ROUND ( (Required Divisor-TRUNC(Required Divisor) )*16)
XR17V258
32
66MHZ PCI BUS OCTAL UART WITH POWER MANAGEMENT SUPPORT
REV. 1.0.2
The closest divisor that is obtainable in the V258 can be calculated using the following formula:
In the formulas above, please note that:
TRUNC (N) = Integer Part of N. For example, TRUNC (5.6) = 5.
ROUND (N) = N rounded towards the closest integer. For example, ROUND (7.3) = 7 and ROUND (9.9) = 10.
