Serial Ports
The ACEs (Asynchronous Communication Elements ACE1 to ACE2) are used to
convert parallel data to a serial format on the transmit side and convert serial data to
parallel on the receiver side. The serial format, in order of transmission and reception,
is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one,
one and half (five-bit format only) or two stop bits. The ACEs are capable of handling
divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter
logic.
Provisions are also included to use this 16x clock to drive the receiver logic, also
included in the ACE a completed MODEM control capability, and a processor
interrupt system that may be software tailored to the computing time required to
handle the communications link.
The following table is a summary of each ACE accessible register
