PCE84C486; PCE84C487
13 DERIVATIVE REGISTERS
The PCE84C486 has 22 Derivative Registers and the PCE84C487 has 26 Derivative Registers. Both devices have one
dummy register associated with the Watchdog Timer; this resides at address 45H. The Derivative Port I/O registers are
located at addresses 00 to 05H. When DP0TR, DP1TR and DP2TR are read the data is read directly from the pin.
However, when DP0R, DP1R and DP2R are read the data is read from the port latch (see Figs 24 to 26 for the port
configuration).
As the PCE84C486 has no 8-bit PWM outputs the PWME2 Register (address 44H) is not used and its contents must be
set to 00H. Registers PWME2, PWM10 to PWM13 and the 4 MSBs of Registers DP2TR and DP2R are only available in
the PCE84C487.
