Notes : 1. These clocks at the CLKO pin are internal clock and its frequency is Fosc/2.
2. When the internal signal of the data latch equals to "1,"
then the data of the RAM and ACC be loaded to SOB.

Figure 12. Timing of the Serial Output Function (SOP R)
In the above description, the low nibble location of the serial input/output register is contributed to the
ACC, and the high nibble is to R. The port status register 2 (PSR2) including BUSY
I,
and BUSY
O
can
be read out or cleared by the MOVA R, PSR2, or CLR PSR2 instruction.
Port Status Register 2 (PSR2)
Port status register 2 is organized as 4-bit binary register (PSR2.0 to PSR2.3). PSR2 is controlled by
the MOVA R, PSR2, and CLR PSR2
instructions. The bit descriptions are as follows:
R
R
0
1

3
PSR2
Note: R means read only.
Bit 0 is reserved.
Bit 1 (BUSY
I):
Serial port input busy flag.
Bit 2 is reserved.
Bit 3 (BUSY
O):
Serial port output busy flag.
