Hi team,
Here's an issue from the customer may need your help:
It is documented as follows in section 4.3.2 of Technical Reference Manual:
Regarding the GIOB[2] pin input multiplexing, Control Register Bit A=Control Register Bit B=PINMMR29[16]. Whether the bit is 1 or 0, the equation A and not(B) is constant equal to = .FLASE. And the equation not(A) or (A and B) is constant equal to = TRUE, i.e. whether PINMMR29[16] is 1 or 0, the GIOB[2] has the F2 pin selected, is that correct?
Above is the multiplexing table in section 4.6, comparing the data sheet of the TMS570LS3137, it can be determined that the PINMMR9 [16:23] byte is used to control the multiplexing of the V10 pins. V10 is multiplexed to GIOB[2] as long as PINMMR9[17] is set; V10 is multiplexed to another function as long as PINMMR9[17] is set to 0. Based on the previous analysis, the GIOB[2] uses the F2 pin, i.e. whether GIOB[2] uses F2 or V10 depends on PINMMR9[17], and PINMMR29[16] has no effect. Is this correct?
Could you help check this case? Thanks.
Best Regards,
Cherry
