Note 1: R3 is not required when Vcc=3.3 V and the charge pump is
enabled (CPE = 1).
Note 2: If JATE support is not required, R21, C12 and C23
may be removed (R21 is effectively 0 ohms) and R4 should
be changed to a 604 ohm, 1/4 W, +- 1%.
Note 3: See Appendix for applications requiring UL 1950
3rd Edition compliance.
