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.
Unimplemented bits in SFRs (labeled ’-’) are X (unknown) at all times. Unless otherwise specied, 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 ‘0’s although they are unknown when read.
[3]
The RSTSRC register reects the cause of the P89LPC906/907/908 reset. Upon a power-up reset, all reset source ags 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.
