[1]
Unimplemented bits in SFRs (labeled ’-’) are X (unknown) at all times. Unless otherwise specified, ones should not be written to these bits since they may be used for other
purposes in future derivatives. The reset values shown for these bits are logic 0s although they are unknown when read.
[2]
All ports are in input-only (high-impedance) state after power-up.
[3]
The RSTSRC register reflects the cause of the P89LPC9102/9103/9107 reset. Upon a power-up reset, all reset source flags are cleared except POF and BOF; the power-on reset
value is xx110000.
[4]
The only reset source that affects these SFRs is power-on reset.
[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]
After reset, the value is 111001x1, i.e., PRE2 to PRE0 are all logic 1s, WDRUN = 1 and WDCLK = 1. WDTOF bit is logic 1 after watchdog timer reset and is logic 0 after power-on
reset. Other resets will not affect WDTOF.
