22.2 Pin Functions
use these pins as key interrupts, this function must be specified by setting the relevant registers (see Table 4-15
Settings When Pins Are Used for Alternate Functions).
22.3 Registers
The key input pins that are used as key interrupts are also used for the other functions shown in Table 22-2. To
(1) Key return mode register (KRM)
The KRM register controls the KR0 to KR7 signals by using the KRM0 to KRM7 bits.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
