during normal operation. For maximum flexibility, an option to jumper to an external pull-up is recommended

for TSTPT_(3:0). Note that adding pull-up to TSTPT_(7:4) may have adverse affects for normal operation and

are not recommended. Note that these external pull-ups are only sampled upon a zero to one transition on

POSENSE and thus changing their configuration after reset has been released does not have any effect until the

next time reset is asserted and released. Table 7-4 defines the test mode selection for 3 of the 16 programmable

scenarios defined by TSTPT_(3:0):
