R/W
Write: 0 for normal operation.
Read: 1 when the transfer is done, 0 when the transfer is pending.
Reserved, write 0 for normal operation.
Reserved, write 0 for normal operation.
Reserved, write 0 for normal operation.
Value to write to the Enable bit. 1 to enable, 0 to mask interrupt. This value is transferred
when the bit 1:0 are 10.
0 will enable the transfer from the uP to the selected counter.
1 will enable the transfer from the selected counter to the uP.
00: Reserved. Do not use.
01: initiate a read or write of the counter value.
10: initiate a read or write of the IRQ enable counter bit.
11: not used.
