RM57L843: PBIST Documentation Question

Part Number: RM57L843

Hello,

There is a discrepency In the PBIST ALGOL / RINFO Descriptions in the Technical Reference section 2.2.4.1 Table 2-5 and Table 2-6.

Using the masks provide in Table 2-5 correctly executes PBIST with the following RINFOL and RINFOU values:

ROM - 0xF to RINFOL, 0x0 to RINFOU

SINGLEPORT RAM - 0x0CFFBFF0 to RINFOL, 0x0 RINFOU

DOUBLEPORT RAM - 0xF0000000h to RINFOL, 0x18 to RINFOU

Table 2-6 supplied RINFO values do not execute properly:

ROM - 0xF to RINFOL, 0x0 to RINFOU

SINGLEPORT RAM - 0x0FFFFFF0 to RINFOL, 0x0 RINFOU

DOUBLEPORT RAM - 0xF0000000h to RINFOL, 0x3F to RINFOU

This causes PBIST to execute in sections labeled as reserved in table 2-5. Should the test use the 2-5 values or is it a true pbist failure when ran against table 2-6 values.

Thanks!
