26.5.5.2 Channel Pointer Status Registers (CPSR[1–4])
This register contains status fields and counters that provide status information regarding the
channel processing of the current descriptor. Bits 15–4 are error statuses. When a channel error
interrupt is generated, bits in this range that are set indicate the source of the error. Table 26-19
describes the CPSR fields.
