3.2.23 PS Register: Page Size Selection
NOTE:
3.2.24 CKP Register: Communication Rate Selection
NOTE:
SMSC TMC2074
PS1-0 (bits 1 to 0)
These bits specify the page size.
When INIMODE of the mode register is set to 1, the value set in this register is selected as the page size.
When INIMODE is set to 0, values in PS1-0 of the external input pin become readable. Refer to section
1.6.8.
To change these bits, be sure to set TXEN to 0 (off-line) beforehand. If these bits change during the on-
line state, a software reset will be executed automatically (the software reset is released automatically).
CKP (bits 2 to 0)
These bits specify the communication rate of the CircLink. When INIMODE of the mode register is set to 1,
the value set in this register is selected as the communication rate. When INIMODE is set to 0, values in
CKP2-0 of the external input pin become readable. Refer to section 1.6.15.
To change these bits, be sure to set TXEN to 0 (off-line) beforehand. If these bits change during the on-
line state a software reset will be executed automatically (the software reset is released automatically).
