hello, in the in the 'Revision 1.0, March 2017' of 'ADuCM302x Ultra Low Power ARM Cortex-M3 MCU with Integrated Power Management Hardware Reference' page '9-2':

the SRAM retention controlled by PMG_TST_SRAM_CTL.BNK1EN and PMG_TST_SRAM_CTL.BNK2EN register.

 

but in the page '9-7':

the PMG_TST_SRAM_CTL.BNK1EN and PMG_TST_SRAM_CTL.BNK2EN register is used for the initialization of SRAM.

can you tell me what the usage about this register?

thank you.
