13.7.5 SSP0 Clock Prescale Register (SSP0CPSR - 0x4004 0010)
13.7.6 SSP0 Interrupt Mask Set/Clear Register (SSP0IMSC - 0x4004 0014)
Table 238: SSP0 Status Register (SSP0SR - address 0x4004 000C bit description
This register controls the factor by which the Prescaler divides the SSP peripheral clock
SSP_PCLK to yield the prescaler clock that is, in turn, divided by the SCR factor in
SSP0CR0, to determine the bit clock.
Table 239: SSP0 Clock Prescale Register (SSP0CPSR - address 0x4004 0010) bit description
Important: the SSP0CPSR value must be properly initialized or the SSP controller will not
be able to transmit data correctly.
In Slave mode, the SSP clock rate provided by the master must not exceed 1/12 of the
SSP peripheral clock selected in
relevant.
In master mode, CPSDVSR
This register controls whether each of the four possible interrupt conditions in the SSP
controller are enabled. Note that ARM uses the word “masked” in the opposite sense from
classic computer terminology, in which “masked” meant “disabled”. ARM uses the word
“masked” to mean “enabled”. To avoid confusion we will not use the word “masked”.

Description
Transmit FIFO Empty. This bit is 1 is the Transmit FIFO is
empty, 0 if not.
Transmit FIFO Not Full. This bit is 0 if the Tx FIFO is full, 1 if not. 1
Receive FIFO Not Empty. This bit is 0 if the Receive FIFO is
empty, 1 if not.
Receive FIFO Full. This bit is 1 if the Receive FIFO is full, 0 if
not.
Busy. This bit is 0 if the SSP0 controller is idle, or 1 if it is
currently sending/receiving a frame and/or the Tx FIFO is not
empty.
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
Description
divided to yield the prescaler output clock. Bit 0 always reads
as 0.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
