Table 5-1576 MSS_MCRC_CRC_CTRL2 Register Field Descriptions

Bit	Field	Type	Reset	Description
31:26	RESERVED5	R	0h
25:24	CH4_MODE	R/W	0h	Channel 4 Mode: 0 0 = Data Capture mode. In this mode, the PSA Signature Register does not compress data when it is written. Any data written to PSA Signature Register is simply captured by PSA Signature Register without any compression. This mode can be used to plant seed value into the PSA register 0 1 = AUTO mode 1 0 = reserved 1 1 = Full-CPU mode
23:18	RESERVED4	R	0h
17:16	CH3_MODE	R/W	0h	Channel 3 Mode: 0 0 = Data Capture mode. In this mode, the PSA Signature Register does not compress data when it is written. Any data written to PSA Signature Register is simply captured by PSA Signature Register without any compression. This mode can be used to plant seed value into the PSA register 0 1 = AUTO mode 1 0 = reserved 1 1 = Full-CPU mode
15:10	RESERVED3	R	0h
9:8	CH2_MODE	R/W	0h	Channel 2 Mode: 0 0 = Data Capture mode. In this mode, the PSA Signature Register does not compress data when it is written. Any data written to PSA Signature Register is simply captured by PSA Signature Register without any compression. This mode can be used to plant seed value into the PSA register 0 1 = AUTO mode 1 0 = reserved 1 1 = Full-CPU mode
7:5	RESERVED2	R	0h
4	CH1_TRACEEN	R/W	0h	Channel 1 Data Trace Enable. When set, the channel is put into data trace mode. The channel snoops on the CPU VBUSM, ITCM, DTCM buses for any read transaction. Any read data on these buses is compressed by the PSA Signature Register. When suspend is on, the PSA Signature Register does not compress any read data on these buses. 0 = Data Trace disable 1 = Data Trace enable
3:2	RESERVED1	R	0h
1:0	CH1_MODE	R/W	0h	Channel 1 Mode: 0 0 = Data Capture mode. In this mode, the PSA Signature Register does not compress data when it is written. Any data written to PSA Signature Register is simply captured by PSA Signature Register without any compression. This mode can be used to plant seed value into the PSA register 0 1 = AUTO mode 1 0 = reserved 1 1 = Full-CPU mode
