3.2.26 PININFO Register: Pin Setup Information
SMSC TMC2074
Current status of several CircLink setup pins except for nMUX, nRWM, nSTALONE, nDSINV, ALEPOL,
NSTPRE2, and WPRE2 can be read. It is useful to find pin setup errors by reading the current status.
CHKTSTP (bit 8) becomes 1 when one of the test pins (nTEST[3:0], nTMODE) becomes Low, thereby
notifying the CircLink being in some test mode.
*1: The nSWAP and W16 pins used to set the CPU bus can read out bit 7 and 6 in either
accesses of 16 bit, 8 bit without swap or 8 bit with swap.
