P0REN/P1REN/P3REN (0xB9, 0xBA, 0xBC)
P0REN, P1REN, P3REN enable Pull-up of port 0, 1 and 3. When each bit area is cleared to ‘0’, the Pull-
up of the corresponding port is enabled.

Name
It controls the TX buffer function for each pin in Port3. When
each bit field is set to ‘0’, the TX buffer of the corresponding pin
outputs the value.
It controls the TX buffer function for each pin in Port1. When
each bit field is set to ‘0’, the TX buffer of the corresponding pin
outputs the value. P1.7 only acts as output.
It controls the TX buffer function for each pin in Port0. When
each bit field is set to ‘0’, the TX buffer of the corresponding pin
outputs the value.
Reserved
It controls the Pull-up function for each pin in Port3. When each
bit field is set to ‘0’, the Pull-up function of the corresponding pin
is operated.
It controls the Pull-up function for each pin in Port1. When each
bit field is set to ‘0’, the Pull-up function of the corresponding pin
is operated.
*P1.7 doesn’t have a control field because it is operated as an
output.
It controls the Pull-up function for each pin in Port0. When each
bit field is set to ‘0’, the Pull-up function of the corresponding pin
is operated.
This register is used for masking the input of P0 pin (Refer to
P0AndSel in P0SEL register).
Controls the wake up of the MCU by an external interrupt when in
the power-down mode.
When this field is ‘0’, the MCU wakes up when INT0 or INT1
signal is high (This is the normal case in the MCU.)
When this field is ‘1’, the MCU is woken up by the wakeup signal
of the SleepTimer. Remote control function can be implemented
by the interrupt service routine of the MCU when the WAKEUP
signal occurs by adjusting the RTDLY value in the Sleep Timer
while either INT0 or INT1 is low.
When this field is set to ‘1’, P0 and P0MSK are ORed per bit. The
bits of the result value are to be ANed and then output to P1.7.
This function is used to implement remote control function.
