[1] All ports are in input only (high impedance) state after power-up.
[2] BRGR1 and BRGR0 must only be written if BRGEN in BRGCON SFR is ‘0’. If any are written while BRGEN = 1, the result is unpredictable.
[3] The RSTSRC register reflects the cause of the P89LPC932 reset. Upon a power-up reset, all reset source flags are cleared except POF and BOF; the power-on reset value is
xx110000.
[4] After reset, the value is 111001x1, i.e., PRE2-PRE0 are all ‘1’, WDRUN = 1 and WDCLK = 1. WDTOF bit is ‘1’ after watchdog reset and is ‘0’ after power-on reset. Other resets will
not affect WDTOF.
[5] On power-on reset, the TRIM SFR is initialized with a factory preprogrammed value. Other resets will not cause initialization of the TRIM register.
[6] The only reset source that affects these SFRs is power-on reset.
