P89LPC952/954

8-bit microcontroller with 10-bit ADC

[1] Indicates SFRs that are bit addressable.

[2] All ports are in input only (high-impedance) state after power-up.

[3] BRGR1_0 and BRGR0_0 must only be written if BRGEN_0 in BRGCON_0 SFR is logic 0. If any are written while BRGEN_0 = 1, the result is unpredictable.

[4] The RSTSRC register reﬂects the cause of the P89LPC952/954 reset. Upon a power-up reset, all reset source ﬂags are cleared except POF and BOF; the power-on reset value is

xx11 0000.

[5] 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.

[6] On power-on reset, the TRIM SFR is initialized with a factory preprogrammed value. Other resets will not cause initialization of the TRIM register.

[7] The only reset source that affects these SFRs is power-on reset.
