9.3.2

Flash Access Timing Settings in CPU mode

The following tables list all settings for a given maximum Core Frequency (through the setting of CLKB or maximum clock modulation)

for Flash read and write access.

9.3.2.1 Flash Read Timing Settings (Synchronous Read)

9.3.2.2 Flash Write Timing Settings (Synchronous Write)

9.3.3

Address Mapping from CPU to Parallel Programming Mode

The following tables show the calculation from CPU addresses to flash macro addresses which are used in parallel

programming.

9.3.3.1 Address Mapping MB91F465Kx

Note: FA result is without 10:0000h offset for parallel Flash programming . Set offset by keeping FA[20] = 1 as described in section

“Parallel Flash programming mode

”.
