Remarks
Only key-on wakeup function of the port whose pull-down transistor is
turned ON by register PU1 is valid.
Only key-on wakeup function of the port whose pull-down transistor is
turned ON by register PU0 is valid.
Key-on wakeup function is always valid.

Table 8 Return source and return condition
(5) Pull-down control register
Registers PU0 and PU1 are 4-bit registers and control the
ON/OFF of pull-down transistor and key-on wakeup function
for ports E0, E1, G and ports D4–D7.
