0: Logic 0 driven on the peripheral's input signal port.

–

1: Logic 1 driven on the peripheral's input signal port.

–

blank: Not Applicable.

NOTE

Configuring two pins to the same input signal is not supported as it can yield unexpected

results. This can be easily prevented with the proper software configuration (Hi-Z mode is not

an input signal).

NOTE

When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that

pad’s behavior is undefined. This should be avoided.

CAUTION

Not all exposed peripherals are supported on all AM572x devices. For

peripherals supported on specific device from AM572x family of products refer

to Table 3-1, Device Comparison Table.

NOTE

Some of the DDR1 and DDR2 signals have an additional state change at the release of porz.

The state that the signals change to at the release of porz is as follows:

drive 0 (OFF) for: ddr1_csn0, ddr1_ck, ddr1_nck, ddr1_casn, ddr1_rasn, ddr1_wen,

ddr1_ba[2:0], ddr1_a[15:0], ddr2_csn0, ddr2_ck, ddr2_nck, ddr2_casn, ddr2_rasn, ddr2_wen,

ddr2_ba[2:0], ddr2_a[15:0].

OFF for: ddr1_ecc_d[7:0], ddr1_dqm[3:0], ddr1_dqm_ecc, ddr1_dqs[3:0], ddr1_dqsn[3:0],

ddr1_dqs_ecc, ddr1_dqsn_ecc, ddr1_d[31:0], ddr2_dqm[3:0], ddr2_dqs[3:0], ddr2_dqsn[3:0],

ddr2_d[31:0].
