3.2.27 PININFO Register: Pin Setup Information
3.2.28 ERRINFO Register: Error Information
Revision 0.1 (06-07-07)
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.
RCNCD2-0 (bits 14 to 12)
These bits represent the reconfiguration-generation-cause code, which is the cause of the RECON bit (bit
2) of COMR0, in three bits. Issuing CLEAR FLAGS command to COMR1 or software reset clears these
bits.
