Figure 28-5. eMIOS200 Output Update Disable Register (EMIOS_OUDR)
Table 28-7. EMIOS_OUDR Field Descriptions
Field Description
OU[31:0] Channel [n] Output Update Disable Bits. When running MCB mode or an output mode, values are written to
registers A2 and B2. OU[n] bits are used to disable transfers from registers A2 to A1 and B2 to B1. Each bit
controls one channel.
0 Transfer enabled. Depending on the operation mode, transfer may occur immediately or in the next period.
Unless stated otherwise, transfer occurs immediately.
1 Transfers disabled.
Note: The PXN21 implements all 32 channels, comprising bits OU31 through OU0. The PXN20 implements only
24 channels, comprising bits OU23 through OU0.

Field Description
UCDIS[31:0] Enable Channel [n] Bit. The UCDIS[n] bit is used to disable each of the unified channels by stopping its
respective clock.
0 UC [n] enabled.
1 UC [n] disabled.
Note: The PXN21 implements all 32 channels, comprising bits UCDIS31 through UCDIS0. The PXN20
implements only 24 channels, comprising bits UCDIS23 through UCDIS0.
