Product data sheet (9397 750 13726). Supersedes data of 2003 May 05 (9397 750 11462).
Modifications:
“Features” section on page 2:
–
second bullet: change from “... between 0.15625 and 40 Hz (6.4 and 0.025 seconds)” to “... between
0.148 Hz and 38 Hz (6.74 and 0.026 seconds)”
“Register description” section on page 5:
–
section “PCS0—Frequency Prescaler 0”: remove “... and PCA953x LED Dimmers” from Note 1 (2 places).
–
section “PCS1—Frequency Prescaler 1”: remove “... and PCA953x LED Dimmers” from Note 1 (2 places).
Add note to section “Input—Input Register” on page 5

Section “Power-on Reset” on page 6 re-written.
Section “External Reset” on page 6: second paragraph changed from “This input requires a pull-up resistor to
V
DD
.” to “This input requires a pull-up resistor to V
DD
if no active connection is used.”.
Figure 13 on page 10: add resistor values
DC Characteristics table on page 12: add (new) Note 1 and its reference at V
POR
.
Add Figures 20 and 21.
