PRODUCTION DATA
I2C Commands to use DP pullup to test DP/DM continuity:
Enable GPIOs and DP Pull-up:
h00, hA0 <-set gpio0 to push-pull output mode
h40, hA0 <-set gpio1 to push-pull output mode
hD5, h28
hD6, h04
hD7, h10 <-DP pullup is now on
hCE, h18
hDC, h15 <-muxes DP / DM status onto GPIO lines
Status Readback Check:
h00 = hA0 <-DM status on bit 4 (normal, DM low)
h40 = hB0 <-DP status on bit 4 (normal, DP high)
h00 = hB0 <-DM status on bit 4 (DP + DM shorted together)
h40 = hA0 <-DP status on bit 4 (DP shorted to ground)
Exit Test Mode:
hB2, h80 <-soft reset (end test)
