(1) There are several memory testing algorithms stored in the PBIST ROM. However, TI recommends the March13N algorithm for
application testing.
(2) ESRAM1: Address 0x08000000 - 0x0800FFFF
(3) ESRAM5: Address 0x08010000 - 0x0801FFFF
(4) ESRAM6: Address 0x08020000 - 0x0802FFFF
The PBIST ROM clock frequency is limited to 100MHz, if 100MHz < HCLK <= HCLKmax, or HCLK, if
HCLK <= 100MHz.
The PBIST ROM clock is divided down from HCLK. The divider is selected by programming the ROM_DIV
field of the Memory Self-Test Global Control Register (MSTGCR) at address 0xFFFFFF58.
