Remarks 1. ×:
Table 4-5. Settings of Port Mode Register and Output Latch When Using Alternate Function
When using the P121 and P122 pins to connect a resonator for the main system clock (X1, X2) or to input
an external clock for the main system clock (EXCLK), the X1 oscillation mode or external clock input mode
must be set by using the clock operation mode select register (OSCCTL) (for details, see 5.3 (1) Clock
operation mode select register (OSCCTL). The reset value of OSCCTL is 00H (all of the P121 and P122
are I/O port pins). At this time, setting of PM121, PM122, P121, and P122 is not necessary.
