All DIO ports on the chip are bi-directional. Each of them consists of a latch (SFR P0 to P3), an output
driver and an input buffer, therefore the MPU can output or read data through any of these ports. Even if
a DIO pin is configured as an output, the state of the pin can still be read by the MPU, for example when
counting pulses issued via DIO pins that are under CE control.
At power-up SEGDIO0-15 are configured as inputs. It is necessary to write PORT_E = 1 (I/O
RAM 0x270C[5]) to enable SEGDIO0-DIO15. The default PORT_E = 0 blocks any momentary
output transient pulses that would otherwise occur when SEGDIO0-15 are reset on power-up.
Clock Stretching (CKCON[2:0], SFR 0x8E)
The CKCON[2:0] field defines the stretch memory cycles that are used for MOVX instructions when
accessing external peripherals. The practical value of this register for the 71M6543 is to guarantee access
to XRAM between CE, MPU, and SPI. The default setting of CKCON[2:0] (001) should be changed to 000
for best performance.
Table 15 shows how the signals of the External Memory Interface change when stretch values are set
from 0 to 7. The widths of the signals are counted in MPU clock cycles. The post-reset state of the
CKCON[2:0] field (001), which is shown in bold in the table, performs the MOVX instructions with a
stretch value equal to 1.

Instruction Set
All instructions of the generic 8051 microcontroller are supported. A complete list of the instruction set
and of the associated op-codes is contained in the 71M654x Software User’s Guide (SUG).
2.4.5
80515 Power Reduction Modes
The 80515 core provides two power reduction modes: Idle Mode and Power-Down Mode. These power
saving modes are invoked by setting the appropriate control bit in the PCON SFR register (SFR 0x87).
Idle Mode halts the MPU while allowing the interrupt, timer, and serial port functions to continue to
operate. Once Idle Mode has been entered, an interrupt event automatically ends Idle Mode. After the
interrupt has been serviced, program execution continues with the instruction immediately following the
instruction that set the Idle Mode bit. To enter Idle Mode, the firmware must set the IDL bit (bit 0) in the
PCON SFR register (SFR 0x87).
