Table 256. Mem-Ap Registers - STMicroelectronics STM32WLEx Reference Manual

RM0461
The address of the AP registers is composed as follows:
•
Bits [7:4]: content of the APBANKSEL[3:0] field in the DP_SELECTR register
(see
•
Bits [3:2]: content of the A(3:2) field of the APACC data register in the JTAG-DP
(see
(see
•
Bits [1:0]: always set to 0
The content of the APSEL[3:0] field of the DP_SELECTR register defines which MEM-AP is
being accessed.
