Notes 1. P20/ANI0 to P27/ANI7 are set in the analog input mode after release of reset.
Remark The functions within arrowheads (<>) can be assigned by setting the input switch control register (ISC).
2. Use the recommended connection above in I/O port mode (see Figure 5-5 Format of Clock
3. Set P31 and P32 as follows when these pins are used for on-chip debug. In this case,
Operation Mode Select Register (OSCCTL)) when these pins are not used.
P31/SEG5/OCD1A and P32/SEG6/OCD1B pins are used only as OCD1A or OCD1B functions.
- P31/SEG5/OCD1A: Set to input mode (PM31 = 1) and port mode (PF31 = 0).
- P32/SEG6/OCD1B: Set to port mode (PF32 = 0).
When P31/SEG5 and P32/SEG6 functions need to be evaluated with on-chip debug, use OCD0A and
OCD0B.
