1930 is connected to a further power supply connector 1932. A
power-channeling circuit 1936 is connected to both supply connectors
1904 and 1932 and to power input RTCPTR of PPU 110. Power-channeling
circuit 1936 has a pair of diodes 1942 and 1944 connected together at
their cathodes and therefrom to power input RTCPWR. Diodes 1942 and
1944 also have their anodes connected separately to connector 1904 for
supply 172 and to connector 1932 via a drain-limiting resistor 1946
for coin cell 1930.
Power management logic circuit section 920B has logic (in circuitry
