Figure 5-12 Timing of the Serial Input Function (SIP R)
(2) When the
SOP R
instruction is executed,
the data will be loaded to the serial output buffer (SOB)
from ACC and the RAM, the low nibble data of SOB is from ACC register and the high nibble data
is from RAM, and bit 3 of port status register 2(PSR2) will be set to "1" (BUSY
O
= 1). Then the P0.0
pin will send out 8 clocks or accept 8 clocks from external device and the data in SOB will be sent
out at the rising or falling edge of the P0.1 pin. After the 8 clocks have been sent, BUSY
O
will be
reset to "0" and EVF.5 will be set to "1." At this time, if IEF.5 has been set (IEF.5 = 1), an interrupt
is executed; if HEF.5 has been set (HEF.5 = 1), the hold state is terminated. Users can check the
status of PSR2.3 (BUSY
O
) to know whether the serial output process is completed or not. If a serial
output process is not completed, but the SOP R instruction is executed again, the data will be lost.
The timing is shown in Figure 5-13.
