RCDIR - RC Status Line Direction Select
Volatile Address = 0x6F; Non-Volatile Address = 0x24
This register controls the direction of the associated status line. When bit
n is 1, status line Sn is an input line. When bit n is 0, status line Sn is an
output line.
On startup, if the ENC01 bit in the RCCTL register is 0, v:RCDIR is set to
nv:RCDIR. If ENC01 is 1 on startup, nv:RCDIR is set by control lines C0
and C1.
An attempt to write this register when nv:RCCTL.ENC01 = 1 results in a
CMD_NACK response.
