5.14.2.9 MCSPI_SYST Register

14.2.9.1 MCSPI_SYST Register (Offset = 124h) [reset = 0h]

This register is used to check the correctness of the system interconnect either internally to peripheral bus, or externally to device IO pads, when the module is configured in system test (SYSTEST) mode.

Table 5-1714 MCSPI_SYST Register Field Descriptions

Bit	Field	Type	Reset	Description
31:12	RESERVED_17	R	0h	Reads returns 0
11	SSB	R/W	0h	Set status bit 1 Force to 1 all status bits of MCSPI_IRQSTATUS register. Writing 1 into this bit sets to 1 all status bits in the MCSPI_IRQSTATUS register. 0 No action. Writing 0 does not clear already set status bits. This bit must be cleared before trying to clear a status bit of the MCSPI_IRQSTATUS register.
10	SPIENDIR	R/W	0h	Set the direction of the SPIEN[3:0] lines and SPICLK line 1 Input (as in peripheral mode) 0 Output (as in controller mode)
9	SPIDATDIR1	R/W	0h	Set the direction of the SPIDAT[1] 1 Input 0 Output
8	SPIDATDIR0	R/W	0h	Set the direction of the SPIDAT[0] 1 Input 0 Output
7	WAKD	R/W	0h	SWAKEUP output [signal data value of internal signal to system] The signal is driven high or low according to the value written into this register bit 1 The pin is driven high. 0 The pin is driven low.
6	SPICLK	R/W	0h	SPICLK line [signal data value] If MCSPI_SYST[SPIENDIR] = 1 [input mode direction], this bit returns the value on the CLKSPI line [high or low], and a write into this bit has no effect If MCSPI_SYST[SPIENDIR] = 0 [output mode direction], the CLKSPI line is driven high or low according to the value written into this register
5	SPIDAT_1	R/W	0h	SPIDAT[1] line [signal data value] If MCSPI_SYST[SPIDATDIR1] = 0 [output mode direction], the SPIDAT[1] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIDATDIR1] = 1 [input mode direction], this bit returns the value on the SPIDAT[1] line [high or low], and a write into this bit has no effect
4	SPIDAT_0	R/W	0h	SPIDAT[0] line [signal data value] If MCSPI_SYST[SPIDATDIR0] = 0 [output mode direction], the SPIDAT[0] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIDATDIR0] = 1 [input mode direction], this bit returns the value on the SPIDAT[0] line [high or low], and a write into this bit has no effect
3	SPIEN_3	R/W	0h	SPIEN[3] line [signal data value] If MCSPI_SYST[SPIENDIR] = 0 [output mode direction], the SPIENT[3] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIENDIR] = 1 [input mode direction], this bit returns the value on the SPIEN[3] line [high or low], and a write into this bit has no effect
2	SPIEN_2	R/W	0h	SPIEN[2] line [signal data value] If MCSPI_SYST[SPIENDIR] = 0 [output mode direction], the SPIENT[2] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIENDIR] = 1 [input mode direction], this bit returns the value on the SPIEN[2] line [high or low], and a write into this bit has no effect
1	SPIEN_1	R/W	0h	SPIEN[1] line [signal data value] If MCSPI_SYST[SPIENDIR] = 0 [output mode direction], the SPIENT[1] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIENDIR] = 1 [input mode direction], this bit returns the value on the SPIEN[1] line [high or low], and a write into this bit has no effect
0	SPIEN_0	R/W	0h	SPIEN[0] line [signal data value] If MCSPI_SYST[SPIENDIR] = 0 [output mode direction], the SPIENT[0] line is driven high or low according to the value written into this register If MCSPI_SYST[SPIENDIR] = 1 [input mode direction], this bit returns the value on the SPIEN[0] line [high or low], and a write into this bit has no effect
