Pull-up control register 0 (Note 1)
b7 b6 b5 b4
Note 1: During memory expansion and microprocessor modes, the pins are not pulled high although
their corresponding register contents can be modified.
Note 2: The pin for which this bit is "1" (pulled high) and the direction bit is "0" (input mode) is pulled high.
Pull-up control register 1
b7 b6 b5 b4
Note 1: The values after hardware reset is as follows:
00000000
00000010
The values after software reset, watchdog timer reset and oscillation stop detection reset are
as follows:
00000000
00000010
"11
Note 2: During memory expansion and microprocessor modes, the pins are not pulled high although
their corresponding register contents can be modified.
Note 3: If the PM01 to PM00 bits are set to "01
in a program during single-chip mode, the PU11 bit becomes "1".
Note 4: The P7
Note 5: The pin for which this bit is "1" (pulled high) and the direction bit is "0" (input mode) is pulled high.
Pull-up control register 2
b7 b6 b5 b4
Note 1: The P8
Note 2: The P9
Note 3: The pin for which this bit is "1" (pulled high) and the direction bit is "0" (input mode) is pulled high.
