• Description: Universal Serial Bus Series Microcontroller
• Manufacturer: ELAN Microelectronics Corp

Product Specification (V1.0) 01.09.2009
(This specification is subject to change without further notice)
The relationship between the prescaler value and these bits are shown below:
CONT [6] Interrupt enable control bit. This bit toggles the Interrupt function between
CONT [7] LED bit. This bit is used to enable the LED sink capacity of P76 and P77.
7.2.3.3
These are I/O port (Port 5 ~ Port 7) direction control registers. Each bit controls the I/O
direction of three I/O ports respectively. When these bits are set to 1, the relative I/O
pins become input pins. Similarly, the I/O pins become outputs when the relative
control bits are cleared.
PSR2/TSR2
The WDT Timing base is 8 ms.
Ex. Prescaler = 1:128
WDT overflow time is: 8 ms × 2

enable and disable. It is set to 1 by the interrupt disable instruction "DISI"
and reset by the interrupt enable instructions "ENI" or "RETI."
0 : Enable the Interrupt function
1 : Disable the Interrupt function
0 : Disable the LED sink capacity of P76, P77
1 : Enable the LED sink capacity of P76, P77
0 : Output direction
1 : Input direction
