NAME
FUNCTION
7
P2S
0: Disable Schmitt trigger inputs on port 2 and enable TTL inputs on port 2.
1: Enables Schmitt trigger inputs on Port 2.
6
P1S
0: Disable Schmitt trigger inputs on port 1 and enable TTL inputs on port 1.
1: Enables Schmitt trigger inputs on Port 1.
5
P0S
0: Disable Schmitt trigger inputs on port 0 and enable TTL inputs on port 0
1: Enables Schmitt trigger inputs on Port 0.
4
ENCLK
1: Enabled clock output to XTAL2 pin (P2.0)
3
T1OE
1: The P0.7 pin is toggled whenever Timer 1 overflows. The output frequency is
therefore one half of the Timer 1 overflow rate.
2
T0OE
1: The P1.2 pin is toggled whenever Timer 0 overflows. The output frequency is
therefore one half of the Timer 0 overflow rate.
1
P2M1.1 To control the output configuration of P2.1.
0
P2M1.0 To control the output configuration of P2.0.
