FUNCTIONAL DESCRIPTION
Microcontroller
The microcontroller is an 80C52 with 16 kbytes of ROM,
256 byte RAM, timers 0, 1, 2 , and 5 I/O ports (port P0:
open-drain; ports P1 to P3: weak pull-up). Port P4 is
identical to 83CE560, except that precharge circuits
ensure fast rise times at end of read mode (transition times
<0.5 µs). The ROM code content can be tested by
signature to avoid reading it out after masking; for security
bit option, see Table 12. The CPU, timers 0 and 1, serial
UART, parallel I/O ports, 256 byte RAM, 16 kbyte ROM
and external bus are conventional C51 family library
elements. Timer 2 is a conventional C52 element
(interrupt enable bit ET2: bit 3 in register IEN1 at byte
address E8H and interrupt priority bit PT2: bit 3 in register
IP1 at byte address F8H.
Register PCON has an added feature: PCON.5 = RFI
(reduced Radio Frequency Interference bit). When set to
logic 1, pin ALE cannot be toggled. ALE clears on RESET.
If access is required to the external data memory via
MOVX instructions (see Table 1), set bit PCON.6 = ARD in
the PCON register to logic 1.
For further information, please refer to the published
specification of the 83CE560 in “Data Handbook IC20;
80C51-Based 8-Bit Microcontrollers”.
Ports P40 to P47, INT0 and P12 to P17 are used internally
for controlling the smart card interface and the other
peripherals. Ports P34 and P35 are used to control the
auxiliary contacts C4 and C8.
The list of differences given in Table 1 may help the
software developer of the dedicated emulation board for
the TDA8006 or other devices.
