ADE5166/ADE5169/ADE5566/ADE5569
A useful implementation of the waterline feature is to determine
the amount of space required for the stack and allow a suitable
default starting address to be selected. This optimizes the use
of the additional XRAM space, allowing it to be used for data
storage. To obtain this information, the waterline should be set
to the estimated stack maximum and the interrupt enabled.
If the stack exceeds the estimated maximum, the interrupt is trig-
gered, and the waterline level should be increased in the interrupt
service routine. Before returning to the main program, the
waterline interrupt status flag (WTRLFG, Bit 0) of the stack
boundary SFR (STCON, Address 0xBF) should be cleared. This
program continues to jump to the waterline service routine
until the stack no longer exceeds the waterline level and the
maximum stack level is determined.

Data Sheet
Interrupt SFR
A two-tiered interrupt system is standard in the 8052 core. The
priority level for each interrupt source is individually select-able
as high or low. The ADE5166/ADE5169/ADE5566/ADE5569
enhance this interrupt system by creating, in essence, a third
interrupt tier for a highest priority power supply management
interrupt, PSM (see the Interrupt System section).
I/O Port SFRs
The 8052 core supports four I/O ports, P0 through P3, where
Port 0 and Port 2 are typically used for access to external code
and data spaces. The ADE5166/ADE5169/ADE5566/ADE5569,
unlike standard 8052 products, provide internal nonvolatile
flash memory so that an external code space is unnecessary.
The on-chip LCD driver requires many pins, some of which are
dedicated for LCD functionality and others that can be configured

as LCD or general-purpose I/O. Due to the limited number of
I/O pins, the ADE5166/ADE5169/ADE5566/ADE5569 do not
allow access to external code and data spaces.
The ADE5166/ADE5169/ADE5566/ADE5569 provide 20 pins
that can be used for general-purpose I/O. These pins are mapped

to Port 0, Port 1, and Port 2 and are accessed through three bit-
addressable 8052 SFRs: P0, P1, and P2. Another enhanced
feature of the ADE5166/ADE5169/ADE5566/ADE5569 is that
the weak pull-ups standard on 8052 Port 1, Port 2, and Port 3
can be disabled to make open-drain outputs, as is standard on
Port 0. The weak pull-ups can be enabled on a pin-by-pin basis
(see the I/O Ports section).
STANDARD 8052 SFRS
The standard 8052 SFRs include the accumulator (ACC), B, PSW,
DPTR, and SP SFRs, as described in the Basic 8052 Registers
section. The 8052 also defines standard timers, serial port inter-
faces, interrupts, I/O ports, and power-down modes.
Timer SFRs
The 8052 contains three 16-bit timers, the identical Timer 0 and
Timer 1, as well as a Timer 2. These timers can also function as
event counters. Timer 2 has a capture feature in which the value
of the timer can be captured in two 8-bit registers upon the
assertion of an external input signal (see the Timers section).
Power Control Register (PCON, Address 0x87)
The 8052 core defines two power-down modes: power-down
and idle. The ADE5166/ADE5169/ADE5566/ADE5569
enhance the power control capability of the traditional 8052
MCU with additional power management functions. The
POWCON SFR (Address 0xC5) is used to define power control
specific functionality for the ADE5166/ADE5169/ADE5566/
ADE5569. The program control SFR (PCON, Address 0x87) is
not bit addressable (see the Power Management section).
The ADE5166/ADE5169/ADE5566/ADE5569 provide many
other peripherals not standard to the 8052 core, for example
Serial Port SFRs
The two full-duplex serial port peripherals each require two
registers: one for setting up the baud rate and other communication
parameters, and another register for the transmit/receive buffer.
The ADE5166/ADE5169/ADE5566/ADE5569 also provide
enhanced serial port functionality with a dedicated timer for
baud rate generation with a fractional divisor and additional
error detec-tion (see the UART Serial Interface section and the
UART2 Serial Interface section.)
