Port P72 peripheral subfunction
0 : CLK2 output
select bit (Enabled when PS1_2 = _{1 : V phase output}
1 and PSL1_2 = 0)
Nothing is assigned.
When write, set "0". When read, the content is indeterminate.
PSC_7 Key input interrupt disable bit
(Note 2)
0 : Enabled
1 : Disabled
Note 1: Set this bit to "0" when PSL1_2 = "1".
Note 2: When this bit is "1", key input interrupt for interrupt controller is disabled
regardless of port input and setting of interrupt control register.
When changing this bit, set key input interrupt disabled by key input interrupt
control register.
