Description

Access control register

Fields

LATENCY

Read latency These bits are used to control the number of wait states used during read operations on both non-volatile memory banks. The application software has to program them to the correct value depending on the embedded Flash memory interface frequency and voltage conditions. Please refer to Table 27 for details. … Note: Embedded Flash does not verify that the configuration is correct.

0 (B_0x0): zero wait state used to read a word from non-volatile memory

1 (B_0x1): one wait state used to read a word from non-volatile memory

2 (B_0x2): two wait states used to read a word from non-volatile memory

7 (B_0x7): six wait states used to read a word from non-volatile memory

15 (B_0xF): fifteen wait states used to read from non-volatile memory

WRHIGHFREQ

Flash signal delay These bits are used to control the delay between non-volatile memory signals during programming operations. Application software has to program them to the correct value depending on the embedded Flash memory interface frequency. Please refer to Table 27 for details. Note: Embedded Flash does not verify that the configuration is correct.
