SMSC TMC2072
- When reading/writing: GPIO Direction Register
nGPOE [7:0] (bit 7-0)
Set the direction of GPIO7-0 pin. The direction can be set by every one bit. nGPOE7 corresponds to the
GPIO7 pin. (Refer to section 2.14.)
0 : Output mode
1 : Input mode
NST register: Network Standard Time
NST15-0 (bits 15 to 0)
These bits indicate the standard time in the network. Refer to section 2.11 - Network Standard Time (NST)
for details.
Accessing the NST register can dynamically provide the latest time data. Since NST is a 16 bit width
counter, it is necessary to read the even address side (10h) first when an 8-bit bus is used. When the even
address side (11h) is read out, the remaining 8 bits of the NST are latched internally.
