BRGR1 and BRGR0 must only be written if BRGEN in BRGCON SFR is logic 0. If any are written while BRGEN = 1, the result is unpredictable.
All ports are in input only (high-impedance) state after power-up.
The RSTSRC register reflects the cause of the P89LPC932A1 reset. Upon a power-up reset, all reset source flags are cleared except POF and BOF; the power-on reset value is
xx11 0000.
The only reset source that affects these SFRs is power-on reset.
On power-on reset, the TRIM SFR is initialized with a factory preprogrammed value. Other resets will not cause initialization of the TRIM register.
After reset, the value is 1110 01x1, i.e., PRE2 to PRE0 are all logic 1, WDRUN = 1 and WDCLK = 1. WDTOF bit is logic 1 after watchdog reset and is logic 0 after power-on reset.
Other resets will not affect WDTOF.
