Bit 6—Input Strobe Interrupt Enable (ISIE): Enables or disables the handshake interrupt
request (ISI).
Bit 6
ISIE
0
1
Description
The handshake interrupt request (ISI) is disabled.
The handshake interrupt request (ISI) is enabled.
(Initial value)
Bit 5—Output Strobe Enable (OSE): Enables or disables output of the output strobe signal. Do
not set OSE to 1 in the expanded modes (modes 1 and 2).
Bit 5
OSE
0
1
Description
The output strobe signal is disabled.
The output strobe signal is enabled.
(Initial value)
Bit 4—Output Strobe Select (OSS): Selects whether to generate an output strobe signal when the
port 3 data register (P3DR) is written, or when it is read.
Bit 4
OSS
0
1
Description
An output strobe signal is output when P3DR is read.
An output strobe signal is output when P3DR is written.
(Initial value)
Bit 3—Latch Enable (LTE): Controls the input latches of port 3. Do not set LTE to 1 in the
expanded modes (modes 1 and 2).
When LTE is set to 1, input data are latched on the falling edge of IS. The data are retained in the
input latch until the port 3 data register (P3DR) is read, after which the next data can be latched.
Bit 3
LTE
0
1
Description
Port 3 input data are not latched.
Port 3 input data are latched on the falling edge of IS.
