405 Note added

Note: * In this example the value of the ABCS bit in SEMRA_0

is 0. When ABCS is set to 1, the basic clock frequency is eight

times the bit rate and the receive data is sampled at the fourth

rising edge of the basic clock.

Section 13 Boundary

Scan Function

449 Description amended

The HD64F2218, HD64F2218U, HD64F2218CU and

HD64F2217CU incorporate a boundary scan function, which is

a serial I/O interface based on the JTAG (Joint Test Action

Group, IEEEStd.1149.1 and IEEE Standard Test Access Port

and Boundary Scan Architecture).
