amb
Applies to external clock, crystal oscillator max 24 MHz.
Maximum frequency =
1 k pull-up resistor on IRQ pin.
RCLK is an internal signal derived from Divisor Latch LSB (DLL) and Divisor Latch MSB (DLM) divisor latches.
= 40 C to +85 C; tolerance of V
Dynamic characteristics - Motorola or 68 mode
