- Port's falling edge interrupt: PORTB ( INT1 ) ! 8-bit Base timer ! LCD driver:
240 dots (1/8 duty 1/4 bias) or 136 dots (1/4 duty 1/3 bias)
! LCD used as scan output ! Built-in dual tone PSG with one noise generator ! 2 Clock sources
OSC: (code option select crystal or RC type)
- Crystal oscillator 32.768K
- RC oscillator: 262K
OSCX: (system register selected ceramic or RC type)
- Ceramic oscillator 455K
- RC oscillator 1.8M or 2M ! Instruction cycle time:
- 122.07µs for 32.768 KHz crystal
