31	16	15	0
	CNT_RE_MAP1		CNT_RE_MAP0
	R/W-0		R/W-0

LEGEND: R/W = Read/Write; R = Read only; -n= value after reset

Table 26. TCP2 Output Parameter Register 2 (TCPOUT2) Field Descriptions

Bit	Field	Value Description
31-16	CNT_RE_MAP1	Number of MAP1 re-encode errors
15-0	CNT_RE_MAP0	Number of MAP0 re-encode errors

6.22 TCP2 Execution Register (TCPEXE)

The TCP2 execution register (TCPEXE) is shown in Figure 52 and described in Table 27.

		Table 27. TCP2 Execution Register (TCPEXE) Field Descriptions
Bit	Field	Value	Description
31-3	Reserved	0	Reserved. The reserved bit location is always read as 0. A value written to this field has no
			effect.
2-0	EXECUTION_INSTR		Execution commands of TCP.
		0	No instruction
		1	Start TCP
		4	Debug mode. Normal initialization and wait in MAP state 0.
		5	Debug mode. Execute one MAP decode and wait in MAP state 6.
		6	Debug mode. Execute remaining MAP decodes and complete normal ending.
		7	SOFT RESET. Soft reset all TCP registers except for the execution register and endian
			register.
