Host system clock. Used to time operations in the Host Interface and clock internal logic. Must be greater
than twice the frequency of highest X1, Counter/Timer, TxC (1x) or RxC (1x) input frequency.
Chip select: Active low. When asserted, allows I/O access to OCTART registers by host CPU. W_RN signal
Used to convey parallel data for serial I/O between the host CPU and the 26C198
Data Acknowledge: Active low. When asserted, it signals that the last transfer of the D lines is complete.
interrupt(s). Open drain.
Interrupt Acknowledge: Active low. When asserted, indicates that the host CPU has initiated an interrupt
Input/Output 0: Multi–use input or output pin for the UART.
Input/Output 1: Multi–use input or output pin for the UART.
Global general purpose outputs, available from any channel.
Master reset: Active Low. Must be asserted at power up and may be asserted at other times to reset and
alternatively be driven by an external clock in this frequency range. Standard frequency = 3.6864 MHz
Crystal 2: If a crystal is used, this is the connection to the second terminal. If a clock signal drives X1, this pin
NOTE: Many output pins will have very fast edges, especially when lightly loaded (less than 20 pf.) These edges may move as fast as 1 to 3 ns
