1.1

Flash read access with fixed wait states

Per default the XMC1100 / XMC1200 / XMC1300 devices use a configuration with

adaptive wait states for read accesses to the flash memory, dynamically adapting to the

system frequency and flash access timing without user software interaction.

Alternatively, it is possible to configure the XMC1100 / XMC1200 / XMC1300 devices to

apply fixed wait states to each flash read access, improving determinism of program

execution from flash. The required number of wait states depends on the system

frequency f_MCLK, as defined in the parameter N_FWSFLASH. The number of wait states can

be configured with the bit NVM_NVMCONF.WS, the selection of adaptive or fixed wait

states is done with the bit NVM_CONFIG1.WS.

Attention: Any write operation to the register NVM_CONFIG1 to switch between

adaptive and fixed wait states configuration must only modify the bit

NVM_CONFIG1.FIXWS. Changing other bits in NVM_CONFIG1 can lead

to unpredictable results.

Attention: Before and after the fixed wait states configuration or the system

frequency f_MCLKis changed, the number of selected wait states must

always comply to the parameter N_FWSFLASH

Below is a code snippet defining the register addresses, configuring one wait state and

then switching to operation with fixed wait states.

Example

// Headers and variables to fix number of wait states to "1"

#define ADDR1 0x40050008

uint32_t * NVM_NVMCONF = (uint32_t *) ADDR1;

#define ADDR2 0x40050048 //Address of NVM_CONFIG1

//Address of NVM_NVMCONF

uint32_t * NVM_CONFIG1 = (uint32_t *) ADDR2;

// init sequence to fix number of wait states to "1"

*NVM_NVMCONF = *NVM_NVMCONF | 0x1000; //Set .WS bit => 1WS

*NVM_CONFIG1 = *NVM_CONFIG1 | 0x0800; //Set .FIXWS bit => fixed
