S3C6400X RISC MICROPROCESSOR
APB BUS clock. When timer value is to be zero, interrupt signal is occurred and CPU can remove trailing bytes in
FIFO.
PACKET NUMBER CONTROL
SPI can control the number of packets to be received in master mode. If there is any number of packets to be
received, just set the SFR(Packet_Count_reg) how many packets have to be received. SPI stops generating
SPICLK when the number of packets is the same as what you set. It is mandatory to follow software or hardware
reset before this function is reloaded. (Software reset can clear all registers except special function registers, but
hardware reset clears all registers.)
NCS CONTROL
nCS can be selected auto control or manual control. In manual control, Auto_n_Manual must be set default value
0. nCS level is decided as the same as that nSSout bit is set. nCS can be toggled between packet and packet in
auto control. Auto_n_Manual is set to 1 and nCS_time_count must be set as long as nCS is inactive. nSSout is
not available at this time.
